I just finished P4 a few weeks ago. Never have I become a fan of a game series so quickly. Would probably double-dip if this came to PS3, but for now I want to make Persona 3 Portable my next foray into this world.
If anyone out there has a Vita, hasn't played P4G, and has even a passing interest in what it might be like to be an exchange student in Japan for a year, play P4G. You'll love it.
They should seriously consider porting Golden to the PS4 (and PS3, if possible). There's just no way I'm going back to pre-Golden Personae considering how that game let you choose which abilities to pass on to new Personae. I can't go back to dice rolls and frustration.
