Does the computer AI cheat?
In the campaign missions and most scenarios, the computer AI usually starts out with preplaced units and buildings, as well as a starting pool of resources. In multiplayer and custom missions, the computer starts out with normal resources and units and follows all the same rules that human players do. The only advantage that the computer AI has is knowledge of the map– while it still must obey line-of-sight and detection limitations, it automatically knows where resources, enemy towns, etc. are located. The AI is also extremely efficient, making it a dangerous opponent.
