How did they go from CMR to bumper cars?
The main problem I have with this game is that the title "Colin McRae" is still in the game. Dirt 2 has absolutely nothing in common with the classic CMR games. The classic rally represents only about 10-15% of the game. The rest is basically bumper cars. This game had so much potential, but it's all wasted on this mindless arcade. If only they would stick with the original CMR concept...
Bottom line; if you never played CMR before and you are looking for a decent racing game - go for it. Dirt 2 is a fun game and it's a real eye candy. Don't expect too much depth though.
If you are CMR fan however - stay away from this game and keep looking for something else.
