Deep Rock Galactic, I play it exclusively on single player with the little robot buddy. On easier modes it’s pretty chill and pauses well if you need to stop in the middle of a mission.

Sable is just a relaxing exploration game. No real combat, just riding through a desert on a hover bike. Cool art style.

Inscryption is a creepy deck builder, with some wild turns. Don’t look up much or spoilers abound.

Moonring is a free old school rpg. Graphics are classic but the game is a great throwback with some modern gameplay.
