I think we both like different things, which is fine.
I would rather see civs that break a few rules then to not see them.
rip AoE3DE
I’d love to see a Chronicles like Spin-off with an Early Moden setting though. But more like inbetween AoE2 and AoE3.
Spin-off that fills the gap between AoE2 and AoE3
I thought about adding them but they would probably feel to modern while not being as unique as the plains tribes.
There are some other potential civs if we look at the western parts of the continent like Pueblo. Haida would also be an option as a naval civilisation but they might not be well known enough.
I think Tomahawks are too iconic for them to not have them. I made them more of a dedicated anti Infantry unit so more like a Hand Cannon or Slinger replacement then a Throwing Axeman. Franks do have Hand Cannons for the actual anti Infantry role.
The Trash Ram could be a 2nd UU or regional unit though.
Maybe they could have a Spearman UU that replaces the Eagle Warrior for them since it doesn’t make too much sense historically. It would then be kinda like the Fire Lance or Temple Guard with a bonus against Cavalry and also with Shock Infantry armour.
That actually sounds like a cool idea. It would work well for a civ with now walls as a way to defend against raids.
