Pokémon Crystal All is a hacked version of the classic Game Boy Color game that throws in every single Pokémon from the first two generations—all 251 of them. No more version-exclusive monsters or trade evolutions blocking your way. You can actually complete the Pokédex solo, which is wild if you grew up with the original.

It still feels like Crystal at its core—same story, same Johto vibes—but now you’ll run into stuff like Houndour way earlier, or find a Dratini chilling in some random patch of grass. The level curve gets a little weird in spots, but hey, that’s part of the charm. If you’ve played Crystal to death but want that "gotta catch ‘em all" rush without jumping through hoops, this is the one.
