I don't care what anyone says; I got the 360 version of the game and I absolutely love it. The characters, story, amazing soundtrack, graphics, battle system, leveling system, EVERYTHING. The only thing I can honestly complain about is Vanille's voice. At times it sounds fine, but most of the time, I honestly cannot stand it.
Other than Vanille, though, I'm really happy with the English cast. Lightning and Sazh are my favorites, but Fang is up there too.
I also want to point out the fact that to me, this feels like one of the most "real" Final Fantasy games I've played. Some of the scenes in the game are handled and acted out so well that they seem almost like a real movie, or a struggle that real people would go through. I can't really put it into words (as you can see, lol) but I absolutely love it.
Edit: Oh, btw, I'm... 12 hours in I think? I got it last night at a Wal Mart here in Los Angeles. I had it pre-ordered at GameStop, but when I saw it at Wal Mart, I just had to get it. So yeah, I got home, and I've been playing ever since! Didn't even go to sleep
And for the record, I loved FFIV, FFIX, FFX, and FFX-2's battle system. Never played FFXII.
Edit: Huh, apparently I'm only 9 hours in. Dunno where the hell I got 12 from.
