Is this the DiRT game we have been waiting for since the original Colin Mcrae: DiRT & DiRT 2? Perhaps it is, as the guys at Codemasters are confident enough to wager DiRT: Rally as the game that its fans are begging them to produce. Check it out here: LINK
Initially launched as an Early Access game on Steam, DiRT: Rally currently offers 14 rally cars, and a number of courses, and is set to be continuously developed with the help of the community. Codemasters also removed Gymkhana mode, in an effort to win the fans back and I think they did with all the launch hype by setting the bar purely for Rally Racing aficionados.
Early Access means that the game is at Alpha or Pre-Alpha stage, so it should take a while for Codemasters to fully release it. In the meantime, you could grab it now and help the devs to develop the game via feedbacks.
