Either it's content didn't satisfy you much or broke your game, let's talk about the bottom of modding communities' content. First one is actually quite contrary, one of top of nexus' network, which name is "A world of pain" for New Vegas. It bloats the worldmap with loads and loads of dungeons and boring copy & pasted quest of kill x or deliver y and various fluff like player houses which does nothing but eats your time on crap and makes you level up too fast. It basically applies Fallout 3 philosophy to New Vegas. Dungeons feels exactly like dungeons instead of real world locations, which is what Fallout 4 suffered later from. Second is everything related to Mothership Zeta for F3. DLC was a chore but playing more of this? No, thanks. Fallout 1.5: Resurrection. Now, as a roleplaying game it's superb but the edgy writing is a complete horseshit alarming about lack of taste of people who wrote text for this total-conversion. Even if it makes sense for NPCs to behave like that in post-nuclear New Mexico, stuff like teenage virgin selling herself to the player character casts a certain thoughts about writers. Original games and Nevada handled dark humor better IMO. Loverslab content for Oblivion is tasteless tentacle anime pandering, makes the game even more unstable at best, ruins it in later perspective and often conflicts with each other and some of the useful mods. Packs of inventory stuff from Baldur's Gate ported to Planescape: Torment. Obviously, doesn't fit into the setting.
