Hey all!
Got my wife a Switch 2 and Pokopia, and watching her play it gave me so much nostalgia to the good old days of Pokémon. Naturally I started googling Pokémon games, but they’ve released so many throughout the years (haven’t played since Pokémon Emerald on my GameBoy lol) that I don’t know which one to pick. So, I thought, let’s ask some veterans! Could you guys point me in the right direction on which games to look into? Brilliant Diamond looks pretty nice tbh, to get that good nostalgia feel but also see what ‘new’ Pokémon have been released (those are probably not even new anymore, but I hope you understand where I’m coming from lol).
Thanks in advance all!
