As far as the decent budget RPGs go. Eternal Sonata, Enchant-Arm(I think this one has both voice tracks as well.), and Tales of Vesperia(which had only 1.). There are several low budget ones that are 1 dvd as well. I'm not sure about Last Remnant. My copy is still in the Amazon box. I'll get to opening it after a finish off a few other games. IU is on two disk and another SE published game that doesn't feature both voice tracks.What JRPGs on the 360 have been on a single disc? BD and LO were 3 and 4, respectively, and I know Star Ocean was multidisc (but I don't know how many). No idea about Last Remnant. Eternal Sonata?
Edit: Oh, wait, doh, Vesperia is a single disc.
