Carmageddon: Max Damage I would play constantly in 3D, until nVidia stopped supporting it. It was so satisfying seeing objects and limbs bouncing off the car and toward the camera in 3D. Hoping I can experience that again at some point.
I’d also love to see Red Faction 1 and 2 in VR.
Also Unreal 2, and Sir, You are Being Hunted.
