Suggestion for VR game?

Recently, my father got interested in VR after trying it at my brother's house. My father used to play games too, but I really did not expected he would get interested in VR. The problem is that I really do not have any idea about what kind of VR games there are, because I barely have experience.. So I searched a bit, downloaded a flight simulation kind of game, and he tried, but he got motion sickness from it. So... I really need some help to find new games for him. Sorry for getting long, so in short:

  1. I need some help to find a game that my father could enjoy. He used to play FPS a lot.
  2. Games that would give little or no motion sickness would be great.
  3. The device is Oculus Quest 2 and PC.

Sorry for bothering you guys, but it's quite long since I saw him getting interested in something so much, I really want him to enjoy using the device. I would be thankful for any help.
