You will always start with a Town Center, a standard number of Villagers and at least 1 scouting unit. You will also start with a Forage bush and near Stone/Gold. The objects that may vary include: * Scout numbers and/or type: your scout can be your civilization’s standard starting Scout, but it can also be a Serjeant or even a Flaming Camel. * The second building, if it spawns: all buildings except for Mill, Mining/Lumber Camp, Docks and Caravanserais can spawn. * Extra resources: far Gold may or may not spawn, while extra resources may spawn scattered across the map. What is guaranteed is that you will never have a 1 TC, 3-6 Villagers, 1 Scout start.
