Firstly, the car graphics yet again surpass CMR02 and CMR03 and the damage model verges on the hilarious; with the game set to advanced mode, you might be attempting to drive up a particularly steep verge, accidentally catch your rear bumper on the ground and go flipping over backwards at 40mph, doors falling off and pieces of fairing wobbling all over the place. This is particularly funny when playing two player- especially when playing with my GF who seems to be able to destroy these cars in ways I didn't think possible at incredibly low speeds(!)
Second up I'd like to say this game is for a real enthusiast. I'm no massive rallier, but I must admit I'm determined to complete this game if it's the last thing I do! If you want to win the bigger, beefier cars you have to come 1st or 2nd in the championships in either normal or advanced. But it ain't that easy. A single blip in your performance, even on normal mode, such as clipping a tree, cutting a verge or clunking your underside on one of those frustrating little treestumps, and you can go from 1st position to 7th in a heartbeat. Make the same mistake on every race and you won't even qualify. In other words, this game is rock solid.
Graphically, I thought perhaps something could've been done about the pixelated backgrounds and fairly boring track verges that seem to have been a constant disappointment in the CMR series, but once you're haring along taking in 90 degree corners at motorway-cruising speeds, your eyes are on the car and the road.
(Easter Egg: note the road signs on the British track say 'ARAF' (welsh for slow) - I could've sworn at some stage these tracks are labelled as being in England, though they are clearly in Wales- a schoolboy error that's sure to get the taffies riled up!)
