世紀帝國III
"Age of Empires" allows players to choose to play either along specialized, story-backed conditions or as individual battles against the AI (and other players). Choosing to battle against the AI – rather than following the storyline – allows the AI to adapt to players' strategies and even remember which games it won and lost. The AI eventually overcomes players' strategies and easily destroys their villages after several games. For instance, in "Age of Empires III," this is referred to as playing a "Skirmish." However "Age of Empires III" allows players to refine their strategies further against the AI by "Building a Deck," which allows players to replace "Home City" shipments with improved alternatives.
