VR games for Christmas ideas?



I’m new to the post and am looking for ideas for my son. He just got a (somewhat cheap, $80) VR headset for his LG phone. He’s interested in a game or 2 for Christmas. I know he has played Zombie Apocalypse and Call of Duty in the past and, presently, is playing Witcher. Any ideas? Or is his set not really good enough for any really good VR gaming?
