You guys should read the closing comments, they don't give it a 10 because it's a perfect game (the subtitle is masterful anyways, not perfect) they give it because it pushes boundaries in a genre and is the best game they have played since Ocarina of Time (which got a 10 and obviously wasn't perfect either).
The reviewing system doesn't work that way, a 10 is a masterful game, not a perfect game, also it's relative to time, a 10 tomorrow is worth more than a 10 today.
As for bribery, it's possible but the game also sounds pretty darn amazing and other websites have given it similar scores, I'm thinking of buying a 360 just for this and then I'll see if the hype was worth it, 10 is amazing, bribery gets you up to a 9.9 but for IGN to give it a 10 (which only Soul Calibur and Ocarina of Time have) means they really do like the game a lot.
Anyways, you guys should call out that they were bribed and the game is repetitive if you HAVEN'T played it, JackAxe, how does that make you different from the hardcore toddlers who give it a 10 without having played it? Have you played GTA IV already? And NO, playing GTA 3, VC , SA, etc does not qualify, they are not the same game.
