Sound Shapes seems to be like a good original game.
Problem is that, Gravity Rush aside, there's nothing new/original due out for the console. Games like Rayman and Wipeout will be great once they drop in price.
My £18 Rayman turned up from Zavvi this morning. More than happy with my Vita at the mo; some brilliant games (Lumines, EG, Wipeout, Disgaea) and all the PSP goodness I could wish for to hand. And yet so many people seem to be selling them already - what were they really expecting from it?
