FNV is great and modding it is such a pain. Although, I recently spent far longer than I’d like to admit wrestling with it, just trying to get one specific mod working, which takes the Fallout parodies of the Cold War to an interesting logical conclusion and lets you join a communist party, complete with damn good satire of leftist infighting. I’ve also had a lot of fun with a Great Patriotic War faction overhaul, significantly better than the Soviet NCR mod I’d used prior to that one. See, you think you just want to add one thing, then there’s other stuff that works well with that thing, and next thing you know you’ve got a rat’s nest of dependencies and the bloody Script Extender AKA recipe for even more volatility and crashes. Basically, I’ve managed to break things in a way that it will inevitably crash a certain amount of time into the save or the session, no matter what progress I do or don’t make, and once it crashes once that save file is busted and loading it will lead to an immediate crash or a crash within minutes.

I gave up and put it aside indefinitely when I reached the point of frustration and hopeless desperation where I was more likely to put a hole through a wall than actually solve anything.
