Just about anything that is turn based. Board games ports, Roguelike games like Balatro, Slay the Spire, 9 Kings. Civilization games and Civ-likes. You can even play ttrpg ports like Baldur’s Gate and Divinity but it might be a little annoying without an RPG mouse. I played a lot of Civ when my left arm was paralyzed then weirdly Wii tennis after surgery.
