You may remember Doritos: Dash of Destruction, a free game that was released in the second half of December on the XBLA and allowed you to take control of a devastating T-Rex, or a delivery van in order to deliver Doritos whilst avoiding the T-Rex.
Microsoft executive Mark Kroese, General Manager of Microsoft’s Entertainment and Devices Advertising Business Group, reported at CES 09 that the game has been downloaded nearly a million times since it was released.
Perhaps the biggest attraction for people was the easy achievements points, you can rack up 200 achievements in under 20mins.
