It seems to me that American PS3 owners are obsessed with graphics, rather that whether or not a game is fun. Take Killzone 2, edge gave it a good score, (7 - which in edge terms means way above average), personally I would have gave it a 6 as it is a generic FPS with great graphics and i'm afraid a generic FPS with great graphics = a generic FPS. On the other hand Half Life 2 is a classic and got the score it deserved (10) - a game like Killzone 2 may have much better graphics than Half Life 2, but that doesn't change the fact it was a far inferior game.
MGS4 got 8 which is a very high score - and accurate in my opinion as although MGS4 was good, the pacing was far too slow and it simply wasn't as much fun as one would of expected. Again, great graphics but that means nothing if a game is quite tedious to play.
PS3 owners complain about Halos textures?? When will they learn that nobody cares, as long as the game looks ok then that's fine, it's the gameplay that counts. If textures were the definition of the quality of games then nobody would be buying Wii's and Mario Kart DS would be one of the worst games of this generation, wheras in reality it is one of the best.
