I've read a lot of things about how New Vegas is a better, more interesting "neo-Fallout" game. Better story, less backtracking, something about not having a train station which by itself makes it a better game.
But I'm wondering, in what ways is Fallout 3 a better game? My gut answer is gameplay, because we all know Obsidian make great interactive games whose only flaw is that they interact like shit. But I could be wrong since I haven't played it! So what is your answer?
Bonus question: I recently got a sick gaming PC and I got NV on Steam, what are the best mods? :D
Edit: I only want mods that make the game pretty and fix well-known issues, nothing that changes the experience since this is my first time.
