Like a timed deathmatch, players keep score of touchdowns and field goals of escorted and unescorted artifacts to the enemy's goal line. Gameplay is described in the scenario instructions.
This is a 2 player football game starting in the Post-Iron Age. Each player begins with plenty of units, huge resources and a sideline full of buildings to replenish lost units. The game is set up so that you have to keep your own score and the football is the artifact which starts at the very center of the map. The game lasts for 40 minutes. I think the game would be more fun if the object was just to get the artifact to the opponent's goal line - then aoe would give you the victory instead of keeping your own score. The map is pretty nicely done and the game should be quite frantic and fun. Nice job!
