Well, hello; i'm new here, didn't think to type in x-box 360 forum in me browser and such? Been looking for a while too, aaaanywhoo.
i'd say; for an FF fan this game will dissapoint. It doesn't have the replay factor (due to the at time infuriating difficulty changes, from very easy to Bladdy hard, and also the level cap - willingly introduced to meff off the power players), also the game lags at times; say at the beggining of a battle the camera stops panning and the screen jumps, leaving you feeling somewhat annoyed that a game can't load it's own content. Also something else, sometimes the scenery looks like it's straight from a ps2 game.
However despite these shortcomings the game does deliver on it's 'aim ring' (though not groundbreaking, it is refreshing) and also the EPIC music supplied throughout. Another thing to note is the witty humour introduced as well as the nice dream stories. This game I believe was slightly overhyped (by those people who went and bought Blue dragon, expecting an epic game, only to find a very repetitive, childish game), so don't jump on this game hoping it'll be the best thing ever, simply because it has some weight amongst the other (cough) very well made other x-box 360 JRPG's.
However do note, this game IS entertaining, it would be well worth the £39, shame however that it had to be compared to such a great title from a completely different platform.
