I am a girl gamer, and I was only born with one hand myself and I have been able to play multiple games like pistol whip. I love playing poker, VR. That might not be what he’s into but it’s really fun and you can play with one hand. There is also VR chat you can go in watch movies play little games talk to other people and I was able to do that with one hand mini golf is really good beat saber. You can put it on one-handed so that comes in handy Zombieland headshot so far. I’ve been able to play that sometimes I have to pick up the other controller to touch something but it’s been working. There’s another game called RacketNX she might like I hope things work out and if anyone else knows any other games, I would love to hear about more. Thank you so much.
