HGSS is so good it makes every other Pokémon game obsolete.
>b-but muh distribution
You can have a full team of Johto Pokémon before the first gym.
>b-but muh level curve
If you find yourself underleveled in HGSS, that's objectively a skill issue. Never happened to me.
>b-but muh houndour
every Pokémon game has Pokémon exclusive to the postgame, this is a literal non-argument. Johto's postgame is also more or less an extension of the main-game, so you can still use it in a large portion of the game.
>b-but muh kanto's backyard
GSC was made as a direct sequel, building off what was already there. It's different, not bad.
>johto was le designed to fail
Kill yourself.
Every "criticism" against HGSS is parroted Pokétuber opinions from fans of inferior games, desperately coping with the fact that HGSS mogs them in every way imaginable.
HGSS is as close to a perfect Pokémon game as we'll ever get.
