Very solid and best of the series so far, though quite challenging and sometimes even frustrating.
Graphics - Cars look overall sharper and shinier. The car's damage system has been improved as well, and you can completely screw over your car if you really tried. Even the wheels have multiple stages of damage: starting with the tire, then to the actual frame. More special effects have been added to the tracks, such as swaying grass, dirt, etc. Still not the best graphics on Xbox though.
Sound - there is NO soundtrack in this game, with the exception of the start menu. The co-driver has a very annoying british accent that does its job well but may become repetitive at times. The car engine sounds are done exceptionally well.
Value - considering the price tag (30 bucks), this game is well worth your money. I still find it a bit lacking in depth though. Though I've played it for more than 10+ hours, I've spent probably more than 1/3 of the time trying over and over again to beat the near-impossible Group B championship.
Overall - I bought it, I liked it, but then it got tiring and I eventually stopped playing it. It was worth my money though. I recommend this game to anyone who has any slight intersest in rally games.
