Ever since I watched Brad play Nuts and Bolts, I have been itching to play a collectathon game. It's been years since I sank extended amounts of time into a game collecting things, but I suddenly really want to.
I only have a Vita, so PSP, PSone, or Vita only. I would also prefer it to be a 3D platformer of some sorts. I know that sort of knocks out a ton of games, but I have too large of a backlog of RPGs to add more.
