Silly question but have you played Skyrim? of all the open world games this to me is the most accessible, and arguably the biggest, especially with all the DLC.
I quit it back in the summer but my brother is still playing it a year on, its such a great game.
I'm actually on the look out for a JRPG that comes close to this quality. Its a shame the genre has falling so far. Xenoblade is probably my best choice but I wouldn't give it a 2nd look based on what I've seen, the style and visual effects just doesn't appeal to me, but all those reviews can't be wrong. I'll pick it up when I get a Wii U. Anyone else know any really good JRPGs on ps3 or 360?
