I hope it’s not the end of new civ DLCs, however if it’s indeed the end I have an alternative solution for those who don’t want new civs yet still desire to have new units to cover more regions or parts of the globe not yet covered.
I always feel that the mercenary or minor civ mechanic in AoE 3 could be implanted in AoE 2. The mercenary units would be trained from the Mercenary House, a building available to all civs in the Castle Age. The mercenary units would cost only gold to train, they aren’t strong enough to tip the balance but it definitely means that gold wars in the game are gonna be more intense with them added.
The mercenary units would vary depending on the map. I have some general ideas regarding this:
For maps without a specified location (such as Black Forest, Highland, Rivers, Nomads, Team Islands, etc.), the units available in the Mercenary House would be European, for instance the Crusader Knight.
For Middle-Eastern themed maps (such as Arabia), the mercenary units would be Middle-Eastern, such as the Hashashim or certain type of camel unit.
For Africa themed maps (Kilimanjaro or Serengeti), the mercenary units would be from not yet covered African civs, such as Assegai Warrior, Kanuri Guard, etc.
For America themed maps (Yucatan, Atacama, etc.) the mercenary units would be those from the not yet covered Native American civs, such as a Purepecha unit (I have no idea about it yet), the Chimu Maceman, the Bolas Warrior, or the Mapuche Malon cavalry.
For Scandinavia or other maps set in Northern Europe, the mercenary units could be Varangian Guard or Danish Axeman.
For Mangrove Jungle or maps set in SE Asia, the mercenary units could be Javanese Cetbang Cannon, Visayan Bagakay Warrior, or Champa Mangpung / Vijaya Raider.
And for any map set in East Asia (for instance the map Mongolia), the mercenary units could be Fire Lancer, Thunderclap Grenadier, or some type of cavalry unit.
Basically the mercenary units serve to cover the civs not yet in the game. After all it’s much easier to introduce some units than introducing a whole new civ.
