LBP and Uncharted are very fun. MGS HD if you haven´t played before. Star Ocean First Departure is a good 5 dollars psp game that you can get on vita digital store.
Persona 4 Golden is not bad, but not as cool as playing on the PS2, or even Persona 3 on the PS2, which were much more scary and were a perfect fit for the big tv screen.
Gravity Rush was a big disapointment for me, because it is made by SCE Project Siren, which is the old Team Silent from Konami, developers of Silent Hill and Siren Blood Curse, my two favorite games. Gravity Rush is nowhere near as good as these titles.
There are a bunch of free PSN Plus games, so I recomend to you this: get on sony online store and get all the free games you can, even before your Vita arrives.
My grammar errors are justified by the fact that I am a brazilian living in Brazil. I am also very stupid.
