How can a 6 hour game be worth a 9? $10 an hour to play the thing to completion. Some people aren't into multiplayer. All I read from this review is I'm a sucker for Halo games. It's one review. It's fine. Hopefully you take it for what it is; one man's opinion. And who judges games by Metacritic? Look at where their scores come from...I use IGN usually, they seem to be very fair with their reviews. If there is a discrepancy, I'll look around. I hope Halo is a 9, but I dont see that being true.
