Id argue this is the best game when it comes to story not just for mystery dungeon but including the main games. Dont be fooled by the cute graphics, this game will tug at your heartstrings.
If youre a pokemon fan, it's a must play.

Id give it 5 stars if it didnt punish you for evolving lol (you and your partner's avatar has only one expression if you evolve)

I would instantly buy a remake if they make one.
