Finish Age of Empires III: The WarChiefs

Rome added to the 1997 original, with four campaigns and the units that fixed its worst balance.

China, Japan and India, each winning by building a wonder rather than collecting one.

Attila, Montezuma and El Cid; the expansion the competitive scene still plays.

Gunpowder, home cities and the colonial era; the awkward middle child of the series.

Thirteen civilisations from the Dark Age to the Imperial Age; still played competitively.

The 2021 return of the medieval RTS with documentary campaigns.

The 1997 original: twelve ancient civilisations, from the Stone Age to the Iron Age.

The expansion adds the Atlanteans and the titan you spend the whole game trying to release.
