I just bought a crystal white Vita 1000 off Ebay and jailbroke it.
Now, I already have
>Lumines Electronic Symphony
>Project Diva f, F2, and X
>Danganronpa 1, 2, and V3 (I already played these on PC)
>Gravity Rush
>Muramasa Rebirth
>Soul Sacrifice Delta
Lumines ES is probably the best version of Lumines and Project Diva is neat, haven't played anything else yet.
What are some other "must haves"?
In terms of weeb stuff, JRPGs and pure VNs aren't my thing but I don't mind rhythm games and "adventure" style VNs like Ace Attorney and Danganronpa.
