There wasn't much to complain about Civilization VI on the App Store besides that it didn't come with any extra content. Aspyr Media fixed that today by adding the Poland Civilization and Vikings Scenario Packs as IAPs.
The Polish Pack includes the complete Polish civilization with Jadwiga, Winged Hussar unit, and the Sukiennice building. It also comes Jadwiga's Legacy scenario. The Viking Pack includes three new Natural Wonders, six new City-States with new tile improvements, and the Vikings, Traders, and Raiders! Scenario.
