Neutral trade units criss cross the map carrying resources that are delivered to the team that finds them first. The team that finds the most of these transports get the advantage, otherwise this is mostly a normal random map. In two team games the transports cross between the teams that are in a line on either side of the map, like Anatolia. There are no transports in games with more than two teams.
There are four terrains with different amounts of resources based on the culture of player 2. Egyptian has little wood but lots of gold, norse has lots of wood but not so much gold, etc.
