I used to love playing 3D games, too. Then I got older and my eyes stopped playing along with the fallacy of 3D/VR. This is normal, and imho is one of the biggest challenges facing the VR industry: as people age, they are less and less able to do VR. Its because you're getting older and your eyes are not as level as they used to be. Our brains are wired to correct the differences in horizon that each eye sees, and applies a filter to the 3D inputs so that we don't get motion sick. As we age, our eyes physically change position, and the brain has to do more work to make this horizon correction - with 3D games, it no longer has all the inputs it needs to do the correction (because 3D games aren't really 3D but rather an imitation of it on a flat plane), and thus you start to feel motion sickness more and more. https://en.wikipedia.org/wiki/Depth_perception#Disorders_affecting_depth_perception https://en.wikipedia.org/wiki/Depth_perception#Disorders_aff...
