Mostly I use ones I find funny, some are kind of helpful. Kinda late to PC gaming in general so it’s been really interesting.
I tend to still play through vanilla at least once before doing anything. When they rereleased mgs3 hd I had to download a mod just to get it, you know…in hd. That was one exception, and I ended up refunding anyway because it’s a bit ridiculous for Konami not to do the bare minimum with a port. I guess the only other exceptions have been the RE2 and 3 remakes which I doubt I’ll ever bother beating legitimately. More about seeing how I can break the games and do some exploration and experimenting with cheats, and model swapping is always fun.
Mgsv has a ton that make the game more interesting, and Nier Automata has a lot of fun ones. Replicant is slowly getting there. Senran Kagura has had a bunch but seems sometimes Nexus is a bit arbitrary when it comes to how prudish they are. Unfortunately a lot of my other games don’t seem to be that popular, or maybe just a lot harder to make mods for.
