I need some recommendations.

I've been playing a lot of Pixel Junk Monsters Deluxe with the girlfriend lately and it's great. I only had to buy the game once (on PSN) and we can play it together-- me on my old PSP and the girlfriend on my Vita.

On the bikeride to work today it occurred to me that I should try to find more games like that (PSP games available on PSN that support local multiplayer) since presumably I can do this with any PSN game for PSP that is compatible with Vita and which supports local multiplayer.

Does anyone have any recommendations?

I'm looking for games which:

- are PSP games
- available on PSN
- for Vita
- support local ad hoc multiplayer
- are good
- are preferably girl compatible (my girlfriend is a girly girl who prefers bright happy games like Ratchet and Clank, but will also play RTS games like Age of Empires, and some sports games like tennis) but I'm open to trying to convince her (but I dont think she'd want a fighting game or racing game)
- bonus points for co op games
