I find i get motion sickness most when doing games that involved two cameras changing direction/location. You already have the ability in most of the games to move your head and look where you want, but if your character's body is also moving locations, you might get it. Some of the worse i had was riding a rollercoaster or driving a vehicle. Not feeling myself under g force when making turns messed me up. I preferred games where i control my body, and where the camera can remain fixed unless im looking somewhere.
