Rhythm games. He loves them and he’s amazing at them.
But since those are few and far between, he branches out and will play multiplayer games like Overwatch, although not really battle royale games. He can be pretty good, since he has quick reflexes. Sometimes he’ll hop servers and work on his foreign language skills.
Typically he sticks with Sony since they have a lot of rhythm games. (Also they have dating sims....)
He’s sick of hearing about walking sims or other chill games (like Animal Crossing or Minecraft). They’re so boring to him that he gets riled up just watching people play.
