PSVita advice. First game to pick.

Uncharted Golden Abyss. Also Little Big Planet is a great game alone.

The first PS Vita game I will get when I buy one will be Persona 4: The Golden. I played the demo of Super Sony Brothers and I thought it was okay, but for around $20 dollars.
Gravity Rush is second.

My first advice is to repack the system and return it.

Uncharted!

I cant wait to get my vita in a month, Will be getting assassins creed with mine.

Best game for Vita are: Gravity Rush, Uncharted Golden Abyss and Most Wanter. AC is great but it's too smart (only 8-9 hour of game) and the online is a sh*t

Metal Gear Solid HD Collection for sure. :D

Pata Pata Pata Pon! Pon Pon Pata Pon! Chacka Chacka Pata Pon! Don DonDon DonDon! FEVER!

i liked little big planet very much :)

edit: i think assassin's creed is very good, however i played it not much

Persona 4 Golden. Hands down.. for a quick list of reviews

My advice would have been to NOT buy a Vita.

Persona 4 Golden!

Metal Gear Solid Collection.

Persona 4 Golden

Uncharted and Assasins are good choices

Super Stardust Delta

Save yourself the money and do not buy it. You'll stop using it shortly after a few weeks.

Either P4G or PS plus. You'll get Gravity Rush, Uncharted, and whatnot with it, or P4G. (I'd get PS+ then save for Golden.)
