Their are good games out for the Vita that I could recommend
Disgaea 3 Vita - If you like JRPG's and haven't played the PS3 version
Gravity Rush - Self-explanatory
Hot Shots Golf World Invitational - It's fun as heck even if u don't lke sports games (I know I don't)
Persona 4 The Golden (October 20) - You don't have to be an JRPG fan to get this. 2 of my friends are getting a Vita just to play this game and I already pre-ordered it
When they made the cross-buy announcement, I finally decided to get a Vita, I had been on the fence before that. I ended up hitting Craigslist pretty hard, eventually talking a guy down from 250 to 220 for the Vita, an 8GB card, and 3 games - UMVC3, Gravity Rush, and MLB 12. It's only the Wifi model (not 3G) but I thought it was still a great deal, especially considering that I would have spent another 60-80 or so because UMVC3 and GR were on my buy list already.
