This is a quick scenario I made in only a half hour. Resources are VERY scarce. You will likely battle your opponent over a berry bush or a small patch of trees. You can also find Gaia soldiers around the map. Also, there is a Allied trading post in the center. It has a market so you can trade. This is made for multi-player only. It won't work right on single player. You can't go to Castle Age. Age II expansion is needed for this scenario. 2 players only!
Each player will start in Dark Age and will have:
1 Town Center
1 Scout Cavalry
Note: there is only one gold mine on the map, so trade will be important for gold. You might want to consider trying to cut of your opponent's trade route.
