The reviews of this game have been WAY too harsh, and I would urge people to at least rent it and make their own opinion.
The graphical problems haven't affected me at all, since I downloaded the game to my hard-drive, so that isn't really an issue for me.
This game, however, can be REALLY frustrating at times. I think the battle system has it's problems. I don't feel there is enough control over the different units, and it is a pain watching your party get wiped out and being powerless to do anything.
The story so far is compelling me to keep playing, and if the ending sucks, well so be it.. seen terrible endings before (Fable 2, Fallout 3)
I agree with the IGN reviewer on the "save anywhere" issue, because I am lazy, and never want to bother saving. Others might not have the same problem.
Either way this game feels like a 7-7.5 to me, maybe some of the reviewers had incredibly high expectation, and are rightfully dissapointed.
I sometimes think that if this would have been a half-assed shooter game, it would have rated at least a 6.5. (They should of called it Gears of Duty: Halo Edition)
