PSP must have games:
Corpse Party
Disgaea series
Fate/extra
Jeanne d'Arc
The Legend of Heroes: Trails in the Sky
Shin Megami Tensei: Persona series (skip 1)
Valkyria Chronicles II
Ys series
ZHP: Unlosing Ranger vs. Darkdeath Evilman
There, that should keep you busy until Vita has some games for it. Apparently Wild Arms XF is good too but unfortunately I haven't played it, and I've filled up my 16GB memory card. Oh well.
Edit: Forgot Corpse Party. fail
