How's this for weird: Publisher O-Games is giving you the chance to win a copy of Gran Turismo 5… if you buy and play its PlayStation Network racing game, Superstars V8 Racing.
Ten copies of the highly-anticipated title will be given away in weekly competitions, which begin on November 12. In-game, global challenges will be posed to players, with the winner taking home a copy of Polyphony Digital's game. Details can be found on the title's Facebook page.
Superstars V8 Racing is $19.99, and is out now. Gran Turismo 5 is out whenever Sony gets around to shipping it to retailers.
