The PC Gamer/Bundle Stars Steam key giveaway has been a fine way to pad out a Steam library with some games you might’ve otherwise missed. Today, they’re giving away the most technically-impressive game of the bunch in GTR Evolution. All you have to do is click on the link, like Bundle Stars on Facebook and enter your e-mail address. They’ve got one million keys to give away, and you also get Race ’07 and the RaceRoom Racing Experience included. If you’re into sim-ish racing experiences, then give this freebie a shot – you’ve got absolutely nothing to do lose by doing so.
