Super Hot and Beat Saber don't cause motion sickness. If you have no idea about how the different kinds of VR movement affect nausea and haven't developed any VR legs, then that's absolutely on you. Especially given that Alyx remains accessible to people prone to motion sickness by giving you the option for teleport locomotion and snap turning instead. I know my limits and while I can use smooth locomotion, I still use snap turning. Don't blame the game if you don't know your limits and it's essentially your first VR game in which you don't stay in a single spot.
