Hail and well-met, adventurer! We're excited to get down to rolling dice with you.
You'll need:
Welcome
"To play Dungeons and Dragons, and to play it well, you don't need to read all the rules, memorize every detail of the game, or master the fine art of rolling funny looking dice. None of those things have any bearing on what's best about the game.
What you need are two things, the first being friends with whom you can share the game. Playing games with your friends is a lot of fun, but D&D does something more than entertain.
Playing D&D is an exercise in collaborative creation. You and your friends create epic stories filled with tension and memorable drama. You create silly in-jokes that make you laugh years later. The dice will be cruel to you, but you will soldier on. Your collective creativity will build stories that you will tell again and again, ranging from the utterly absurd to the stuff of legend.
If you don't have immediate friends interested in playing, don't worry. There's a special alchemy that takes place around a D&D table that nothing else can match. Play the game with someone enough, and the two of your are likely to end up friends. It's a cool side effect of the game. Your next gaming group is as close as the nearest game store, online forum, or gaming convention.
The second thing you need is a lively imagination or, more importantly, the willingness to use whatever imagination you have. You don't need to be a master storyteller or a brilliant artist. You just need to aspire to create, to have the courage of someone who is willing to build something and share it with others.
Above all else, D&D is yours. The friendships you make around the table will be unique to you. The adventures you embark on, the characters you create, the memories you make - these will be yours. D&D is your personal corner of the universe, a place where you have free reign to do as you wish.
Go forth now. Read the rules of the game and the story of its worlds, but always remember that you are the one who brings them to life. They are nothing without the spark of life that you give them."
