It would appear most of these reviews are XBOX360 reviews or PC reviews which are not revealing the whole truth, IGN (Not the best reviewer i know) is refusing to review the PC version due to the amount of crashes/broken mechanics in the review code they were given.
They're planning to review the retail version on Steam tonight.
