My 2 cents. I get dizzy watching fps gameplay usually, this is actually the first shooter I've been able to play

My solution for this game is to play in tablet mode, somehow it's ok for me when the screen is smaller. That, or standing very far away from my TV.

Definitely try adjusting the sensitivity of the motion controls. I turned down mine to -2.5. Also, get used to the controls, don't shake (especially vertically) too much. I steady my hands by putting them on my lap.

Play the single player campaign to get used to moving around and rotating the camera. Especially if you're new to shooters.

Hope you can overcome the motion sickness, this game is addictive

Glad to hear that
