I'm looking at DIvinity: Original Sin Enhanced Edition, and I notice it says it has co-op.

What's the co-op like? Can you play the single player campaign in co-op mode, with the full story and everything that you would get in the single player experience?

I haven't personally played co-op, but I have a good friend who played OS1 and OS2 through with co-op, and he said that the story is the single player campaign, just split in between both party members for each bit of dialogue tree, choices, etc.

Basically in single player, the computer controls what your party member says and responds to, but in co-op, it's your friend/family member/loved one.
