I think the only review that matters is your own. I never really agreed with IGN reviews. Some games that are truely awful they big up and games that are good get some poor reviews.
What annoys me about reviews is there seems to be no actual set guidline by which to review them with, some games will get certain things ripped apart while in other games that same thing will be ignored.
Gamespot and Eurogamer are the 2 places i generally agree with.
As with all games there will be things you like and things you don't. With Final Fantasy i am surprised reviewers have decided to be quite picky with it. Like i get the impression they wanted the game to stay a true JRPG, the fact they tried to be a bit western in it didn't go down so well. Which is silly. Whatever the reviewers say i would not care, if they gace it 1% it would still be a day one purchase for me as it has been a longtime since i played a FF game.
