Vanilla quests are very linear with no real choices and when there are there's no real reward or consequences. LoreRim fixes this greatly expanding the choices the player can make for greater immersion
Mod author JaySerpa has expanded many vanilla quest mods which actually have choices in them. These include:
The Heart of Dibella - Quest Expansion
Nilheim - Misc Quest Expansion
Caught Red Handed - Quest Expansion
Infiltration - Quest Expansion
The Only Cure - Quest Expansion
House of Horrors - Quest Expansion
The Whispering Door - Quest Expansion
Daedric quests in Skyrim don't leave much room for player choice often forcing you to serve them and often do bad deeds in order to finish the quest. LoreRim fixes this with a plethora of mods.
To start with we've already mentioned JaySerpa's mods which does 3 of these quests already: The Whispering Door (Mephala), The Only Cure (Peryite), House of Horrors (Molag Bal) all of which allow you to refus to serve them. Additionally Mephala’s Curse: Addon to “The Whispering Door.” by MadAborModding adds a functioning curse to the Ebony Blade and new world encounters. Now the player must find a way to destroy the Blade or succumbing to Mephala is inevitable.
Speaking of MadAborModding mods, several other mods are included which improve some Daedric quests. Boethiah's Calling - Alternate Questline adds a fully voiced alternate questline to obtain the Ebony Mail. Now a "friend" can trick and try to sacrifice you! The Taste of Death - Quest Addon (Namira) adds new dialogue, enemies, and gameplay to the vanilla quest "The Taste of Death". Confront the cult of Namira and bring them to justice. Mehrunes Dagon's Shrine Unlocked - Pieces of the Past Alternate Ending Adds methods to enter Mehrunes Dagon's Shrine without helping Silus Vesuius or having to side with Mehrunes Dagon. Additionally, you can reforge the Razer yourself without Dagon if skilled enough. This mod was designed for player characters that aren't evil but still want to loot the shrine or purge the Daedra within.
Several side missions and misc quests have improved deom their vanilla counterpart.
A Lovely Letter Alternate Routes - Tell Sven and Faendal that you won't get involved in their quarrel, or expose both of them and gain Camilla's favour for yourself.
Mr. Ebony... Get Lost - Skip or play the silly Ebony Warrior quest.
Save the Icerunner - Lights Out Alternate Routes - Jaree-Ra in Solitude has a plan to set up a shipwreck. The ship is said to be full of weapons and riches, ripe for the taking. What will you do?
Golden Claw - More Choices/Silence is Golden/Buyable Golden Claw - Decide whether to keep the Golden Claw
Toying With The Dead - minor Quest Expansion - Adds an optional objective to a miscellaneous quest and turns it into a side quest.
Search and Seizure - Quest Expansion - Increases the available options in the vanilla quest Search and Seizure.
