Achievements make this game as without them you wouldnt slog through all the different modes.
The score would have been a lot lower if I had bought the game as it s not the sort of game I would like to spend £39.99 on.
This game is easy enough for people who want to enlarge their gamerscore as in just a few days I earned 750 points and thats without using the xbox live option. The ranks go from 1 to 10 and I am told that it can take as little as a few hours to rank up to the maximum level so if that is true the replay value on live will also wear thin after a while.
An option to customise the cars would be excellent even if it wasnt up to the standard of Forza motorsport as it would make the online experience a load better showing off your cars etc...
