This is one of the busiest years in terms of jrpgs... I'm so broke I'm gonna have to prioritize and limit my list to 3, I can pick 4 in case tales of xillia gets delayed in Europe.
So far my list is:
Atelier ayesha
Tales of xillia
Ni no kuni
Final fantasy xiii lightning returns
If anymore RPGs get announced I'm screwed and I'm already totally neglecting my Vita.
