Dissidia: Final Fantasy (Well, it's a fightning game, but playing as Final Fantasy's villains feels so good)
Hexyz Force (a translated J-RPG, sadly doesn't have a japanese voice choice)
Phantasy Star 2: Infinity (Tons of customizable things, but I think it doesn't have a translated version)
Riviera: the Promised Land (More like a VN with gameplay, can change between japanese or english voice)
