Green Man Gaming has Dirt Rally for PC for $17.99. The coupon code SUMMER2017 takes another 15% off to $15.29. The purchase gives you a Steam key.
This is Virtual Reality compatible, for those of us who recently got an Oculus Rift deal. Make sure you’ve gotten used to VR, though, as racing games tend to be more prone to nausea.
