so...

if you like pokemon for the collectibility, you should totally get into platformers if you haven't already. personally i immediately thought of jak and daxter, but the first game in the series, jak and daxter: the precursor legacy. most people know the series for its later games which are significantly different from the first game; they introduced guns and lots of vehicle stuff to where it was more of a third person shooter adventure, much like ratchet and clank.
if you like pokemon for the rpg element, i recommend the world ends with you and an indie RPG maker game called "OFF". while twewy is real-time based, OFF on the other hand is turn-based. they're both unique games that mean very much to me and have great stories and characters
