@ starcraft: You know as well as I do you would probably be countering this exact same thing if it were said the other way around.
Aside from that: The IGN video review said NOTHING coming close to the words "best yet on consoles", unless you were watching and reading a different review?
And if it were a scale that moved with time, then ME2 would've gotten ten as it would've been the new standard (i.e. better than Uncharted 2 in the graphical department).
About taking it at face value: that's just why it's impossible to deduce what is meant, because language (in practice) cannot be taken at face value as something is always implied, whether it be the true meaning of the word or something different. To then state it as a 'most certainly what he said' is the exact same spin as the other party is using to dismiss it. We will never know unless that IGN-reviewer clarifies.
