The only VR game that has had staying power among my friends is VTOL VR. VTOL is a combat flight sim based around near future jets and helicopters. This is where I see the greatest growth potential in VR, in simulators and stationary immersive experiences. Walking around is cumbersome and aiming with physical controllers doesn't feel as clean as M&K, but sitting in a cockpit and pushing buttons while the world flies around you at mach 2 feels amazing.
