There are, but I don't tend to play any of them.
I know they have Minecraft in VR which is probably really cool. Beat Saber is a very popular rhythm based game. There is a cool Darth Vader Star Wars game that is probably pretty appropriate if your son or daughter is into Star Wars and there is a really neat art program called Tilt Brush.
I know there are a lot more because I see them in passing in the Oculus store, but I just can't really recommend them since I know really nothing about them. My oldest daughter is only 7, so I do not let her use my headsets. I think 13 is a great age to get started and 13+ is what is recommended for the Quest 2.
Let us know what you find, and more importantly, what your son or daughter thinks of VR!
