There are some games you probably wouldnt like him playing and there are plenty games that you would be comfortable with.

Do you have a vr capable pc? If not i suggest you get an oculus quest.

Some of the games you guys might enjoy are beat saber, rec room, vader immortal (3 parter). Job and vacation simulator, creed, some pong pong and racket games.

Ive got 2 headsets right now. I want to get more so we can all play together. Youngest is 4. Oldest is 8. We have a blast.
