the only reason to burn this person is because this review, while from a worthless source, is inane. instead of saying " i wanted co-op, but there is none so im giving it a mark against its score" he could have said "even though this game has no co-op mode i wont hold it against the game, seeing as though the developers have said many times "ES games will never be co-op/multiplayer" im giving this game what it deserves based on what was presented." basically the person who wrote the article said the only reason why it received a 9/10 is due to lack of co-op.... which makes his review invalid seeing as though TES will not ever be a co-op game, was never presented as a co-op game, or even hinted that it might have been a multiplayer.
The fact that you're saying had it had that it would've got 10/10 should tell you all you need to know about the quality of that "review".
Is Skyrim good? Great even? Most probably yes (I haven't played it yet). So then, we'll give it a 7 or 8 (as that warrants - thats well above what should be average '5').. maybe, just maybe a 9. If our computers literally turned to gold when we played it, and we began excreting cash and urinating beer just from exposure to such sheer amazingness.
But a 10? So it's perfect? No one aspect could be faulted? Nothing improved? I think not. Bethesda themselves certainly would disagree.
