I intend to set up the AI optimally.
The maps I referred to are listed in a sticky in the "Scenario's, Map and Mods" page of this forum.
I edited my original post to include that you need to decide if your co-op should be adjacent or scattered about the map, but you posted before I was complete. So that is one more decision for you to make.
I will make the game hard, but not impossible. Of course that is by my standards. But I am very, very far from being the best player in the world,

so it should be reasonable. That will mean there is a chance that it could pull off a rush on a co-op capital, with a little luck on the AI's part.
