Video game design is the part of game development focused on creating fun and engaging experiences. It does this by combining story, mechanics, rules, and systems to challenge the player’s goals. At its heart, good game design is about matching what the player wants to do with the experience the designer wants to create a principle that applies to all types of games
Game design can be broken down as the following:
Gameplay is the interaction between the player, the mechanics and the systems
Game mechanics are anything that the player uses to interact with the game, or that the game uses to interact with the player.
Systems are the wheels that spin inside the game, either in response to player actions or on their own.
Core loops are the repeatable sequences the players engage in that make up the gameplay
The theory of balance is the concept that all in-game opportunities, choices and strategies available to the player should be equally viable to maintain player engagement and satisfaction throughout the gaming experience.
Balance is the most well known and obvious aspect of a game’s design to players. Poor balance can lead to frustration or boredom, as players may find the game too difficult or easy. Meanwhile, a well balanced game encourages players to explore different strategies, promotes competitiveness, and fosters player retention.
It’s the game designer’s task to ensure all game elements – from character abilities, levels, and weaponry to economic systems are fair and that a player’s success is determined by skill rather than an unfair advantage.
Designers use a range of tools throughout the design and development process to find balance. These tools include play-testing, statistical analysis and player. Balancing aims to create an engaging and exciting gaming ecosystem that satisfies different player styles and preferences.
Balance is often one of the hardest aspects of game design to pull off, especially in multiplayer and RPG games. For this reason, although balance may be a consideration when creating a design document. A balance pass is just about the last thing to be done in a video game’s development cycle. Many modern games are released unevenly balanced, and it’s not until months later that the game is rebalanced.
The theory of repetition is about engaging players through repeated patterns of actions. Repetition of core mechanics, strategies, and tasks keeps players hooked and encourages them to advance further. The strategic use of repetition helps games feel challenging, immersive, and enjoyable.
A good example is a shooting game; the player’s continual task is to aim and fire, which is the core repetitive process. But this repetitive task can be kept interesting by introducing different enemies, levels, and rewards.
Game designers must balance repetition and novelty to ensure the game remains interesting. Design elements like escalating difficulty, rewards, and story progression make this possible.
The theory of contrast is about using the differences in elements, such as difficulty, characters, environments, or mechanics, to create engaging gaming experiences. Contrast is used to relay information, evoke emotions, or create tension and excitement in games.
For instance, contrasting bright and dark colors can highlight perilous areas, while contrasting difficulty levels can amplify a player’s sense of achievement upon overcoming tough obstacles. Contrast in character abilities can also emphasize their uniqueness, driving players to explore different playstyles. Furthermore, contrasts in game pacing—tranquil exploration phases interspersed with intense combat—can sustain player engagement, preventing monotony.
Contrast in game design helps emphasise key aspects of the game, differentiate gameplay mechanics, enhance player decision-making, and guide the player's focus. By intentionally contrasting elements, game designers can draw attention, evoke emotions, and enhance the overall experience.
1. Contrast in Visual Design
Visual contrast refers to differences in color, brightness, shape, or size that help players easily identify important elements in the game world. This can be used to direct the player’s attention, create visual clarity, and reinforce the narrative or thematic elements.
For example, bright red buttons might stand out against a darker background to signal importance or danger, while a dark and muted color palette in a horror game can create tension, making bright lights or objects appear even more striking.
Examples:
In Hollow Knight, the dark, moody environments are contrasted by bright enemy attacks or important objects, making them easier to identify and navigate.
In Overwatch, character designs and abilities are often contrasted with the environment, making it easier for players to spot important items or threats on the battlefield.
2. Contrast in Gameplay Mechanics
The contrast between different gameplay mechanics can enhance player engagement by offering variety and making each element of the game feel more distinct. These contrasts can be seen in the differences between fast-paced action versus slower, strategic moments, or puzzles versus combat.
For example, a game might alternate between intense combat sequences and quieter exploration or puzzle-solving moments, allowing players to enjoy a break from the tension and experience the game from different angles.
Examples:
In The Legend of Zelda: Breath of the Wild, players experience contrasts between peaceful exploration, puzzle-solving in shrines, and intense combat moments.
In Celeste, the game shifts between difficult platforming and more reflective story-driven moments, creating a sense of balance and contrast that enhances emotional depth.
3. Contrast in Narrative Themes
Thematic contrast in game design can be used to explore opposing ideas, creating depth and emotional resonance. Contrasting themes—such as light versus dark, good versus evil, or hope versus despair—can help drive the narrative and deepen player investment.
Games can use contrasts in story arcs or characters to highlight changes, progress, or emotional shifts. For example, a character might evolve from weak to strong, or a peaceful village might turn into a war-torn battleground.
Examples:
Spec Ops: The Line contrasts the typical "heroic military action" with the psychological and emotional toll of violence and war, forcing players to confront the consequences of their actions.
Inside contrasts its dark, oppressive world with the player’s brief moments of freedom or escape, amplifying the feeling of isolation and hopelessness.
4. Contrast in Difficulty and Pace
A balance of contrasting game difficulty and pacing keeps players engaged without overwhelming them or making things too easy. By alternating between periods of high intensity and calm, designers can maintain player interest and create a sense of progression.
This contrast in difficulty is particularly important in games with leveling or progression systems. Players need both challenging moments to keep them engaged and easier moments to allow for mastery, exploration, and relaxation.
Examples:
In Dark Souls, the contrast between calm exploration and intense, punishing boss battles helps emphasize the stakes and creates a satisfying ebb and flow.
Super Mario Bros. uses contrasting difficulty levels between levels, where some levels are designed to be easier to give players a sense of accomplishment, and others are more challenging to provide tension.
5. Contrast in Sound and Music
Music and sound design can create contrast to underscore emotional shifts, highlight important events, or emphasize the atmosphere of different game areas. Sudden shifts in music or the volume of sound effects can cue the player about an imminent change in gameplay or narrative.
For example, a serene, calming soundtrack can be used during peaceful exploration, and a sudden shift to intense, high-tempo music can signal a fight or major event.
Examples:
In Journey, the music shifts from tranquil and atmospheric to intense and dramatic during key moments, mirroring the player’s progression through the game.
Red Dead Redemption 2 uses contrasts between quiet, reflective moments of nature and the loud, chaotic sounds of battle or the urban environment.
6. Contrast in Player Choices and Morality
The contrast between different player choices and moral dilemmas can create meaningful decisions that have lasting consequences in the game world. This could be a choice between a "good" and "evil" path, or decisions that impact characters, story outcomes, or the game’s environment.
These contrasts in player choice challenge players to think about their values and actions, increasing emotional investment in the game.
Examples:
In The Witcher 3, Geralt is often faced with morally ambiguous choices that create a contrast between different approaches to solving problems, such as deciding whether to help or harm others based on the context.
Fable uses contrast between the good and evil paths to create a dynamic change in the world, allowing players to witness the impact of their decisions.
Guiding the Player’s Attention: Contrast helps direct the player's focus toward key elements, such as enemies, objectives, or important items, ensuring they can navigate the game effectively.
Enhancing Emotional Impact: Contrasting elements—whether in gameplay, narrative, or visuals—can increase the emotional impact of specific moments, like the contrast between moments of peace and intense action or the juxtaposition of a happy ending after a long journey.
Creating Variety and Engagement: By contrasting different elements like pacing, difficulty, and gameplay mechanics, designers can keep players engaged without making the experience feel monotonous.
Deepening the Narrative: Using contrast in story elements, such as the juxtaposition of opposing forces or ideologies, can give a game’s narrative depth and complexity, leading to a more immersive and thought-provoking experience.
Reinforcing Themes: Contrast can be used to emphasize the underlying themes of a game, helping players engage more deeply with its message or core ideas.
Overuse: Too much contrast in design elements can lead to confusion or visual clutter, overwhelming the player instead of enhancing the experience.
Balancing: Finding the right balance between contrasting elements (e.g., difficulty, narrative tones, visual styles) can be tricky, and poor balance can disrupt the flow of gameplay or narrative.
Cohesion: While contrast is a powerful tool, it must be used carefully to maintain a cohesive overall experience. Overly contrasting elements might break immersion or disrupt the game's tone.
The Game Design Theory of Emergence refers to the phenomenon where complex and unexpected gameplay experiences arise from simple rules, systems, or interactions within a game. In emergent gameplay, the combination of relatively basic mechanics or game systems can lead to surprising, dynamic, and sometimes unpredictable outcomes that weren’t directly designed or anticipated by the game’s creators.
Emergence in game design is often about player creativity and system interactions, where players interact with the game world and its mechanics in ways that lead to new, often unforeseen, gameplay experiences. This concept is a powerful tool in game design because it can make games feel more open-ended, flexible, and engaging.
1. Simple Rules, Complex Outcomes
Emergent systems are often based on simple, core rules or mechanics, but when those rules interact with each other, they can create intricate, unpredictable, or complex outcomes. These outcomes might not have been explicitly planned by the developers, but they arise naturally from the interactions between systems.
For example, in games like Minecraft, the relatively simple mechanics of mining, crafting, and building can lead to vast, complex player creations, each different from the next.
2. Player-Driven Emergence
A core feature of emergent gameplay is player agency. It relies heavily on how players use their creativity, problem-solving skills, and experimentation to exploit the game’s systems and rules in novel ways.
For example, in a game like Grand Theft Auto, players may interact with the game’s world by performing stunts, creating chaos, or inventing new strategies in ways that the developers never directly designed, but still feel satisfying and enjoyable.
3. Dynamic Systems and Interaction
Emergent gameplay is often driven by dynamic systems that evolve as the player interacts with them. This might include systems like AI behaviors, weather systems, physics engines, or economy simulations that interact with each other in ways that can create new challenges or opportunities.
An example of dynamic systems leading to emergent gameplay is found in Left 4 Dead, where the game’s AI Director controls the pacing and intensity of the game. The Director adjusts enemy placement, resources, and event timing based on how the players are performing, leading to different challenges on each playthrough.
4. Non-Linear Experiences
Emergent gameplay often leads to non-linear experiences because players can approach the game in many different ways. They can discover new strategies or unexpected outcomes through their actions, resulting in gameplay that feels less scripted and more open-ended.
For example, in The Sims, players can manipulate the game’s systems to create complex, often hilarious stories, such as building dysfunctional homes or creating complex relationships between characters. These outcomes emerge from the game’s simulation of daily life, which has rules but allows for a huge variety of possibilities.
5. Feedback Loops
Many emergent systems involve positive or negative feedback loops. These loops occur when a player’s action within the game system results in a cascading series of consequences that either reinforce or counteract the player’s actions.
In a strategy game like Civilization, an early decision to focus on economic development might lead to a snowball effect where the player becomes stronger and more influential over time, making the original choice more impactful. This emergent dynamic comes from the interaction between systems like resource management, diplomacy, and military strategy.
6. Unpredictability and Replayability
Emergent gameplay often leads to unpredictability in the game experience, making it highly replayable. Since the outcomes depend on the player's actions and the interactions between systems, no two playthroughs are exactly the same, even in games with similar mechanics.
This unpredictability can be seen in games like Kerbal Space Program, where players can experiment with the game's physics engine and design spaceships. Each mission has a level of unpredictability in terms of whether or not the player’s rocket will succeed, creating a sense of excitement and discovery.
Minecraft:
In Minecraft, the simplicity of the game’s mechanics—mining, crafting, and building—can result in an immense variety of player-created worlds and experiences. A player may start with the goal of surviving in a world, but through experimentation, creativity, and collaboration, they might end up building massive structures, automating systems, or creating intricate redstone circuits.
The Sims:
The Sims is another excellent example of emergent gameplay. Players have the freedom to create characters, design homes, and interact with a simulated world. While the developers provided the basic simulation (relationships, jobs, and activities), the interactions between these systems create spontaneous and often humorous situations (e.g., characters getting stuck in a pool because they don’t know how to swim).
Left 4 Dead:
The Left 4 Dead series features an AI Director that dynamically adjusts the game’s difficulty by altering the number of enemies and the placement of resources. This system creates emergent moments where players can never predict the exact challenge they will face, leading to unique and unpredictable gameplay experiences.
Spore:
Spore allows players to create and evolve life forms, develop civilisations, and explore space. While the game has some structured progression, the player’s creative input in the evolution and development of their species creates emergent experiences that vary dramatically from one playthrough to another.
Creativity and Freedom: Emergent gameplay provides players with more freedom and encourages creative problem-solving and experimentation, making the game feel less linear and more open-ended.
Replayability: Because the outcomes are unpredictable, players are likely to return to the game multiple times to explore new possibilities and scenarios.
Player Agency: Emergent systems allow players to influence the game in ways that feel meaningful, rather than simply following a scripted path.
Engagement and Discovery: Players often discover new systems, interactions, or strategies that they hadn’t anticipated, making the game world feel rich, dynamic, and alive.
Unintended Outcomes: Emergent systems can sometimes lead to unintended or imbalanced outcomes. For example, a player might exploit a system in ways the developers did not foresee, potentially breaking the game’s intended challenge or balance.
Difficulty in Predicting Player Behavior: Since emergent gameplay relies on how players engage with the game’s systems, it can be challenging to design for every possible player action or interaction. Developers may have to balance the openness of the system with constraints to ensure the game remains fun and functional.
Complexity in Development: Creating a game with emergent systems can be complex, as it requires designing interlocking systems that interact with each other in a way that feels natural and engaging.
The Game Design Theory of Non-Linearity refers to the concept that a game’s progression or narrative does not have to follow a strict, predetermined path. Instead, it allows for multiple potential outcomes, decisions, and paths that the player can choose from, creating a more open, dynamic, and personalised experience. Non-linearity in game design encourages player choice, freedom, and exploration, and it can be applied to various aspects of a game, from the story to gameplay mechanics.
Here are some key aspects of Non-Linearity in game design:
One of the most common forms of non-linearity is found in the narrative structure of games. Instead of a fixed, linear storyline where the player follows a set progression from beginning to end, branching narratives allow the player to make choices that influence the story's direction.
Examples: The Witcher 3, Mass Effect, Detroit: Become Human — where players' decisions can lead to different story arcs, character relationships, and endings.
Non-linearity is often present in open-world games, where players can choose how they want to explore the game world, when they want to tackle certain quests, and in which order.
These games often feature a wide range of activities and objectives that the player can engage with in any order, giving them freedom to approach the game at their own pace.
Examples: The Elder Scrolls V: Skyrim, Breath of the Wild — where players can explore, complete quests, or focus on side activities without following a specific narrative order.
Non-linear design often allows multiple ways to solve challenges or obstacles, rather than having a single, fixed solution. This creates a sense of player agency and encourages experimentation.
For example, a player might face a puzzle, an enemy encounter, or a mission that can be solved through different approaches, like combat, stealth, negotiation, or even creative use of game mechanics.
Examples: Deus Ex, Dishonored — where players can tackle objectives through various approaches, such as violent, stealthy, or diplomatic methods.
Non-linearity allows for more player-driven progression. Rather than a predetermined linear path, players can choose how they want to improve or develop their character, select their missions, and control their progression through the game.
This form of progression can be seen in many role-playing games (RPGs) where the player can freely select skills, abilities, and how they want to approach the game's challenges.
Emergent gameplay arises when the interactions of relatively simple mechanics create complex, unpredictable outcomes. Non-linearity allows for these emergent situations to occur naturally within the game, where the player might experience unique gameplay moments based on their actions.
Games like Minecraft and The Sims allow players to create their own stories or situations within a system of loosely defined rules, offering a non-linear experience that evolves based on their actions.
Non-linear games tend to have high replayability because players can make different choices, take different routes, or engage with different systems on subsequent playthroughs. This encourages players to explore the game more thoroughly and to experience it in new ways.
Non-linearity allows a game to feel fresh even after multiple playthroughs because no two experiences are exactly alike.
Non-linearity also manifests in game systems that adapt and evolve based on player choices, environmental conditions, or random events. This can involve dynamic AI behavior, shifting world states, or the influence of player actions on the game world.
Example: Left 4 Dead uses an AI Director that changes the pacing of the game, controlling the placement of enemies and resources based on how the players are performing.
Player Agency: Non-linearity empowers players to make decisions that affect the game world or narrative, allowing for a more personalized and engaging experience.
Replayability: The ability to explore different choices, paths, and solutions can encourage players to return to the game and experience new things each time.
Immersion and Engagement: Non-linear games often feel more immersive, as players feel like they have control over their actions and the world responds to them.
Creativity: It gives players the freedom to experiment with different strategies and solutions, promoting creativity in gameplay.
Complexity in Design: Designing non-linear games can be more difficult as it requires multiple pathways, branching narratives, and systems that must work together cohesively.
Storytelling Challenges: Maintaining a coherent and engaging story in a non-linear game can be tough, as the narrative must adapt to the player's choices without feeling disjointed or forced.
Balancing Player Choices: Non-linear games must ensure that all choices feel meaningful, without any single path or option overshadowing others or feeling like a "right" choice.
The Game Design Theory of Proximity refers to how the spatial relationship between game elements—such as characters, objects, goals, and obstacles—affects the player's experience and interaction within a game. Proximity in game design can influence how players perceive challenges, rewards, and the flow of gameplay. Here are a few key aspects of this theory:
Designers often use proximity to guide players through environments and shape behaviour. For instance, strategically placing resources in a survival game or positioning key elements in a puzzle game impacts the player’s approach. Placing tall buildings on a 3D map can make a game world more understandable, acting as signposts for the player to investigate.
Physical Proximity (Spatial Arrangement):
This refers to how close or far apart objects or characters are within the game world. For example, in platformers, how close platforms are to each other can impact the difficulty of jumping across them. If enemies are placed too close together, it can increase difficulty, whereas if they are far apart, it may lower the challenge.
Properly balanced proximity in game design ensures that players can navigate challenges without feeling overwhelmed or under-challenged. The distance between obstacles, rewards, or objectives is carefully considered to guide player movement and decision-making.
Proximity and Tension:
In many games, the proximity between the player and certain threats or rewards creates tension. For example, enemies closing in on the player can create a feeling of urgency. Conversely, the proximity of rewards can motivate players to keep going or explore further.
Game designers often use proximity to control pacing—by manipulating how close or far enemies, objectives, or hazards are, they can create spikes of tension and moments of calm.
Proximity and Interactivity:
Proximity can also affect how players interact with objects or other characters in the game. The closer interactive elements are to the player, the easier it is to engage with them. For example, items or power-ups placed near the player encourage exploration and reward curiosity.
Psychological Proximity:
This type of proximity relates to the emotional or cognitive closeness the player feels to in-game characters, objectives, or the narrative. For instance, if a game's story or characters are "close" in terms of emotional engagement, the player may feel more invested in the game. Games that make players feel attached or connected to the world or its characters often use proximity to foster these emotional bonds.
