>>56476835Emerald is only carried by the post-game, aside from maybe two battles the game is a total stompfest and evil teams use a total of 2 pokemon each
HGSS is only carried by nostalgia and cool neat features like following pokemon because it did fuck nothing to fix the issues in GSC, most notably level curve
I don't really know if there's better options for the top4 though. I could argue FRLG deserve the spot more but these games have problems too, and also haven't fixed multiple issues from the original game. I'd definitely put PLA in the top4 though. The only downside to that game are graphics, but it's not exactly a mainline game.
Regardless of favourites, I think we can all agree that BDSP is the worst though as all it provides is fixing the speed of DP for 60$ when emulators can do that for free.
