>>44479476Crystal is generally considered "better," but it's actually possible to catch all three legendary beasts in GS immediately after waking them up, whereas Suicune is locked behind more story progression in Crystal. You can catch all of them with only three badges if you are autistic enough to grind up a Zubat from Union Cave into a level 40 Crobat with Mean Look (like I did).
Also, friendly reminder that only Gens 1 and 2 are Satoshi Tajiri's original vision of what Pokemon is supposed to be.
