Three of Codemaster’s racing games: GRID (2008), DiRT 3 (2011), and F1 2013 (2013), have surprisingly disappeared from Steam, as noticed by Reddit users. While you can still play the games if you had already had them in your Library, they are no longer to be found on Steam Store. No official notification was released that would explain the reasons behind the removal or at least acknowledge the fact. Nor do we know if this is just a temporary hiccup or a lasting decision.
Similarly, GRID was taken down from GOG a couple of days ago, after a big sale in which you could buy it for as little as $3. That decision was made due to GRID’s expiring licenses, GOG told PC Gamer, so it’s likely that the same thing is going on with the Steam versions of the aforementioned titles. It’s possible, though, that the games will return to the stores, as it happened with the early installments of the Fallout series on GOG – at the end of 2014 Fallout, Fallout 2, and Fallout Tactics were removed from GOG, but have returned since.
However, if you have felt a sudden urge to buy these racing games, they are still being sold, except for DiRT 3, on Humble Store with keys redeemable on Steam.
