Has anybody played this cooperatively with a friend vs AI? 

Big questions is it stable does it have connection issues? 

I understand that you would need a powerful PC and a very robust internet to make this work properly. 

I’ve gotten my friend into 4X games and we are playing a bunch of Civ 5 but I would like to mix this into the lineup. I’m a former RTS player but I enjoy the more relaxed pace of 4X plus the ability to save and pick up the next day is nice if something comes up we just pause and play another time.
