>>94185611New Faction: Spirits. Literally just the spirits units, agents, plus normal human militia units for numbers. Everyone is hostile to you when you play them, and they are always hostile to you if you don't play them. Total dicks, and they have no currency/resources, but you can loot tons of spirit artifacts from them
Tribes feature: You can incorporate non-aligned human factions via diplomacy, even if you don't share the same faction type. Not actually a new feature, you can just confederate way, way faster without paying gold or doing marriages.
Map: Very different, lots more islands, and the Earth Nation continent isn't one unified continent in this era. Apparently millennia of war, and huge Avatar events completely reshaped the world in between the time of the Wan and ATLA campaigns. The world campaign was supposed to let you even "sink" or "raise" certain parts of the map for custom games to reflect how much bending can fuck the world, but the devs chickened out and just let you pick only three pre-set variations of the map in different eras.
