Persona 2's story is amazing, but it hasn't aged well AT ALL. I don't need Social Links or P5's fancy dungeons; I just want a game that changes the battle system and Demon Negotiation to something more snappy (earning EXP for the latter would also be nice). Also, make the Velvet Room more modern. Negotiating for special currency rather than a new Persona is probably the most tedious part of the game.
As for games in the poll, I'm torn somewhere in between Skies of Arcadia and Suikoden II. I haven't really played much of either, but I've enjoyed my [EXTREMELY casual] playthrough of the first Suikoden. Skies of Arcadia is also really cool, and it's a world I'd like to see rendered with modern technology.
