Name all the civilizations of the game Age of Empires 2.
Including the 9 extensions: The Age of Kings, The Conquerors, Forgotten Empires, African Kingdoms, Rise of the Rajas, The Last Khans, Lords of the West, Dawn of the Dukes, Dynasties of India & Mountain Conquerors..
It throws me off that the final 's' in names isn't required. E.g., "Celt" is accepted. Making the 's' required would actually make this quiz flow better and feel less awkward since we always refer to them in plural during game-speak anyway.
