Thrones & Patriots will include, among other things, six new playable nations, including the Iroquois, the Lakota, the Persians, the Dutch, the Americans, and the Indians. Like in the original game, each nation will have different themes, special abilities, and unique units. According to executive producer Tim Train, the new nations won't just serve as generic content additions. They'll actually have abilities that modify the core game and may even require seasoned veterans to take a second look at their favorite strategies.
