What are the best couch/local co-op PC games?

Divinity: Original Sin 2 is an indie classic-style RPG with more polish, content, and depth than most games of its generation. You play as a Godwoken, a sourceror chosen by god, who sets out on a journey to change the world.

It's time for a new Divinity. Choose your race and origin story and see how differently the world reacts. Gather your party and blast your opponents with different elements in deep tactical turn-based combat. Explore a vast world alone or with up to 4 players in drop-in/drop-out cooperative play.
