Motion sickness can occur with any first person game that uses transitions, panning, or real time 3D movement. It's very important to have speed controls to minimize motion sickness. It also helps for movement to be smooth. "Bobbing" is bad, as is jerky movement. Not everyone is susceptible to motion sickness, but for those who are, it is a major concern to be able to slow down and smooth out movement.

The panning is very smooth and there appears to be a motion speed control feature. I liked the speed I had with the default mode - which is set in the mid range, so I left it where it was.
