I completed a NV playthrough last December, and here are some of the newer mods I installed that I really enjoyed: Many of them add minor functionality to the game, some of them enhance the audiovisual experience, some add new lore-friendly locations (A World of Pain in particular adds an underground maintenance network that connects many parts of the wasteland), some alter the world in other interesting ways, etc The New Bison Steve Hotel and Lucky Casino It's a lot of mods, though, so if you don't want to download and attempt to install them all, just go ahead and search each individually on the Nexus. I always add these mods and then pick and choose what I'll add on top of them. This is a list of mods which I consider to be essential.
