In the Caribbean, each alliance party is on the same island (if it is a free battle, each person has an island), and there is also an uninhabited island with trade routes on it

Ceylon , each person is on an island (a small island with limited resources). There is a big island in the center of the map. You must land on the uninhabited big island to continue development

Borneo, everyone is on the same island A large island with indigenous people and trade routes. The ocean is rich in resources but not a landing type

Mashu Island (Japan) is similar to Borneo but there are only indigenous people on the island and no trade routes. Trade routes On a piece of land at the edge of the map

Amazon, the player and the opponent are on opposite ends of the river. If you want to attack the opponent, you must cross the river (although it is a land map, you must build a ship to attack the opponent)

< p>The Caribbean is the one that best meets your requirements. By the way, I would like to remind you that the naval battle in Age of Empires 3 consumes the most resources. If there are too many people and too many ships, it will be easy to get stuck. If there are too many players, it is best to play on the land map
