I have a Rift SDK. Motion sickness is very present (for me) in games like Minecraft; however, in a demo like Titans of Space, where your character is stationery in a spaceship (and only the spaceship moves, but you can look around of course) I don't get motion sickness at all. I hear that positional tracking could improve the motion sickness situation.
