Admittedly I'm new to the series, so I'm a little sketchy on the gameplay. Is it an MMO where you are required to connect to the PSN? Or can it be played single player?
From the trailer I'm under the impression this is, at least, derived from "classical" JRPG gameplay. But not like the online game, where the core gameplay isn't really similar to "classical" JRPG's.
