Firaxis has announced two more of the nine cultures being added to Civilization 5's Brave New World expansion. Indonesia and Morocco will join the set, joining Poland, Brazil, Assyria, Zulu, and Portugal, with two civilizations still remaining to be revealed.
Indonesia will be led by Gajah Mada, the Prime Minister of the Majapahit Empire from the 14th century. They'll get a bonus for taking to the seas, as your first three cities formed on new continents get two luxury resources from the Spice Islanders ability. It also replaces the swordsman with the Kris Swordsman, who gets a random upgrade after the first combat, and the Candi replaces the Garden, complete with a faith bonus.
Morocco is led by Ahmad al-Mansur. It is centered around the new trade route mechanics coming in Brave New World, since they get bonuses to gold and culture for each external trade route from the Gateway to Africa ability. Cavalry is replaced by Berber Cavalry, which gets combat bonuses on home turf or on desert. The Kasbah improvement grants extra defense, food, production, and gold to desert tiles as well.
