Gods Eater Burst will work if you can download it to a PS3 then transfer, it's a mix of Monster Hunter and JRPGs. Remember that the Persona Series has a very different take on story telling then the rest of the SMT family, with Persona focusing on social interactions in a modern high school setting. And more traditional combat system with a hint of pet monster training. It's probably worth giving a try. Dissidia might be up your alley too. As for actual VITA Games, I can't reccomend Wipeout 2048 enough, as well as Hot Shots Golf.
