Persona 4: Golden. Good God, Persona 4: Golden. I loved the original on PS2 and the Vita version has cleaner graphics, new voice acting, new storylines, new dungeon content. So yeah, get that. It’s the best RPG I’ve ever played, bar none, and you get to play the updated port before I do, which is something I’ll forever envy you for.
Be aware though- the game can really kick the shit out of you, difficulty wise. Don’t feel bad about using a guide. Or three (like I did).
