Don't see how it can get such a high score. Halo had a huge problem: it was very repetitive. I still remember slogging through what seemed like hundreds of identical corridors, killing hundreds of identical enemies and then having to get out the same way I got in. I know the reason was the tiny amount of RAM on the original Xbox, but I don't know why the same problem on the newer Xbox 360 doesn't detract heavily from the score.
