I wouldn't recommend A Hat in Time, the local co-op is really bad because of how the camera works. :(
A few steam games I know:
ibb & obb
Dinasty Warriors 8
We played on PS but also available for pc:
It Takes Two
Stardew Valley
Children of Morta
Divinity: Original Sin 2
Cuphead
Guacamelee
Moon Hunters
Out of Space
I really wish Josh would make a video about Atlantica Online.
