I must admit i don't agree with the 1 star reviews, i think this is a borderline mediocre/good game. However, there are some blatant faults.
The story is way too short, i got the 1000g in about 6-7 hours ( im not as good as everyone else!). Also, there is no online so there is no replayability and the likelihood is once you get the 1000g it won't enter your xbox again.
However, the machines are good and can make the odd part tricky and graphically it is quite good. But all in all, i am glad i only rented this because i got it on the friday and by the end of saturday i was done with it. So this game is a case of either renting, or waiting for the price to drop.
