As others have said, true movement and turning is an option in a good number of games. Having tried it myself, I won't do it again. I had a headache that lasted several hours as a result. Honestly, I was surprised how much it affected me, given that I've never had any form of motion sickness before or since. My brain did not like the perception of movement disconnected from sensing that movement.

Now, when omnidirectional treadmills become a thing so I can literally walk / run places in games, I'm onboard.
