Really, how far does a series have to drift away from its original premise before it all gets a bit ridiculous? Bar the appearance of the Scotsman’s name in the after-race placings and the fact that it’s an off-road racing game, finding elements that link DiRT to previous titles in the Colin McRae series is something of a challenge. Where have Colin and Nicky Grist disappeared to? Why has everything gone transatlantic? Why is the very first thing you hear when you start the game the voice of US pro-racer and X-games gold medallist Travis Pastrana? Do you want to play a rally game in which your co-driver addresses you as dude?
