When this came out it was a dream come true.
As a kid I always wanted to -be- a pokemon, they're way cooler than people, animals are cool, they are indeed.
Leaving that to the side, the game is one of the best if not the best mystery dungeon out there. Adds the bits of pokemon that make it outstand over the rest and truly makes a memorable experience, unlike most of the things at the time (and still today).
