While the control schemes can be a little jarring, I've not had a major issue with them. For me, it's games that have you accelerate at an incredible pace -- I tried playing HL2 Episode 1, for instance, and have found that to be the most jarring/motion-sickness inducing experience so far. So much so that I went out and got a Razer Hydra to give myself manual control of the acceleration (well, this was a convenient excuse, anyway!).
