-House/Bunker
-Weapon retexture and texture pack
-Weather and better skies, think Nevada Skies
-More weapons, especially shotguns
-Quests, definitely something to side with Enclave, as long as it doesn't change too much in the world, like "The Eagle Has Landed"
-New NPC's and creatures
Edit: Oops, could a mod move this to the mods section?
