I 'll get straight to the point. Here is the link to my scenario.
I made this to have coop fun with a good friend, but then I asked myself why not share?
If you try it out please come here and leave some comments and thoughts so I can further polish it.
Also, one thing I am struggling with is inconsistent AI. One of the enemy AIs never gathers enough food to advance to the next age. Any suggestions are welcome.
EDIT: After extensive trial and error, it seems that making P3 similar to P2 solves the “advance-to-the-next-age issue”. Now P3 (Team 2) and P2 (Team 1) start with a packed Town Center.
