Each map contains 90-100 Villagers, Text, 30-45k resources, 15-17 shipments, 200 population, 4-5 Asian Towers, and Dock Wagons for the Governor's Maps. Governor's Maps include Infantry Mercenaries, Presidents Maps either Cavalry Mercenaries, Buccaneers, or Native Warriors.
These maps include:
NE Lake Baikal
NE Nile Delta
NE America Random
NE Altas Mountains
NE Nile Flood
NE Trade Routes
Place in My Documents -- My Games -- Age of Empires III -- RMS3 and select Custom Maps to play.
For Asian Dynasties. Also for NE, but I'm not sure Coureurs spawn in NE like usual.
NE Sinai is the only one slightly buggy, but 85% of the units and buildings spawn every time.
