Downloaded this as soon it became available on the Marketplace, its a game Ive not been sure on since its announcement, so before passing completely or wasting money, this is the decider.
Graphically, its identical to DiRT 3, apart from the Cars which have been Modified for Bashing and Crashing. This was to be expected anyway, they've not given it a great deal of time for a massive graphics overhaul.
Gameplay, I can see this game being a lot of fun. The cars handle the exact same way as on DiRT 3, but this time you have Boost. They've brought back Tour mode, which should give the player a lot of content to enjoy, including Cars to unlock, Liveries etc.. the same as DiRT 3 again. But then Joyride mode has been added, unfortunately you cant access that through the demo, but this should explain and demonstrate what it contains. Then we have MultiPlayer, which will definitely be giving people hours of enjoyment. I loved the MP on DiRT 3, but this has more of a comedic element to it. People will still be doing everything possible to win, but you wont really care when smashing into the tail of your friend to send them spinning.
This game gets a Thumbs Up from me, and I'll be Preordering soon. I can only recommend you try the Demo, as I know there will be people out there that wont like this.
