>>57904971 (OP)I haven't played all of the games or played too many of them recently, so I can't really state which I think is the best overall, but RGBY hold up really well because it feels like there's a really minimal level of bullshit. Once you beat Brock or so it feels like there's a decent amount of options for team composition or what order you want to do things etc.
I really like GSC and I think they have a lot of QOL improvements over Gen 1, but by comparison the beginning of the game just feels so fucking slow. I'm not even completely sure why since conceptually a lot of the early-game stuff is pretty similar. It feels like if you could have your first badge in Gen 1 in the same amount of time it'd take you to arrive at Violet City in Gen 2, and that your Gen 2 starter is more likely to be overleveled as well.
