These aren't my favourites. More of an expansion on Kanto, Johto feels quite lacking (something they brought more life to in the remakes). You can catch Kanto Pokémon the whole game, yet there are Johto mons that aren't available until the postgame, which takes place in Kanto. I think to me these are some of the only games in the series that feel like they lack their own identity, and it's personal preference but a lot of the Pokémon designs themselves are quite plain. Not you raikou, I love you.
