Hey I suggest you to visit this community: www.gamezhero.com There are lots of new unique games and most of them are developed upon popular cartoons and stories. Have fun!
Also an all-time favourite game is Altitude. It's incredibly silly but it's a lot of fun, and I think it's gone free by now. The game is an online 2D dogfighting game, with cartoonish planes that have a ridiculous selection of weapons and powerups.
I'm just replaying games now - Diablo 3, Game of Thrones, and Guacamelee. I'll start something new soon though - is there any Diablo-style game for the Vita?
