The Drinkbox games Tales from Space: Mutant Blob Attacks and Guacamelee are 2 very very nice games!
Had to get the local service train home from work tonight. Sat playing KillZone on it. The gun play on the game is so satisfying! I'm blown away by how well it plays and hope they can just use the game engine to quickly/cheaply pump some more decent FPS games out for Vita now.
