OK here goes...
Xbox/ Xbox 360; Tales of Vesperia, Lost Odyssey, FF13 & ff13-2 ( Not the greatest of JRPGs but the combat system is simple enough and will get you into the right head space), and the first two maybe three Ateleir games
PS3; Tales of Graces, Nino Khuni Wrath of the White Witch, Star Ocean: the last hope, any FF title you can grab online along with any of Star Ocean/Dragon Quest/Tales of titles, Persona games 1 to 3 (also good on the PSP), Chrono Trigger (again online), Xenogears
PSVITA; PERSONA 4 THE GOLDEN, PERSONA 4 THE GOLDEN, PERSONA 4 THE GOLDEN, PERSONA 4 THE GOLDEN, PERSONA 4 THE GOLDEN
Wii; Forget the Wii. The few JRPGS it has are (with one clear exception, Xenoblade) bland, gimmicky and overall just inferior to the games on any other platform. Just skip it and save yourself from the disappointment that is this system.
PS/ PS2; (To many to list here are a few personal favorites and games with either upcoming sequels or are just really good) Kingdom Hearts 1 & 2, Dragon Quest 8, Tales of the Abyss, Tales of Legendia, XenoSaga Trilogy, Final Fantaies 6, 7, 9, and 12, the Wild Arms Series, Legend of Dragoon, Ateleir Iris and the Mana Khemia games, and the Suikoden games (though these are a little on the harder side with a lot of grind)
Game Cube; Tales of Symphonia, FF Crystal Chronicles, Fire Emblem Path of Radiance
