I hadn’t heard of the Skræling ballistae. That’s very interesting but probably more applicable to potential natives in AoE2 or AoE4.
I don’t think Haida swivel gun canoes would be applicable to use for all natives, but if Haida we’re introduced as a faction they would have solid options. The Haida captured full ships so they would have had full sized cannons and cannon canoes could be plausible for them. They also threw big rocks from their canoes so they’d have options for shorter range siege attacks.
For the rest of the natives, some civ specific ships could fill the siege role. Instead of a ship in the Monitor role, it would make more sense if they had ships in the Galleon role that would have the siege unit tag to make them resilient to building fire and the ability to train units to go after targets further inland. New naval mechanics like melee attacks, boarding, and capturing.
Lakota: Bull Boat
- Trains Warhut units
- Tagged as a siege unit to resist building fire
- Very low attack
- Capable at capturing larger ships
Haudenosaunee: Cheemaun
- Basically equivalent to a Galleon
- Trains Warhut units
- Tagged as a siege unit to resist building fire
Aztec: Tlaloc Canoe
- Alter it’s role to be more in line with other native ships
- Trains Warhut units
- Tagged as a siege unit to resist building fire
Inca: Balsa Boat or Reed Boat
- Add a new boat to fill the Canoe role
- Rework ####### Rafts to fill the stronger ship roles (this censorship is ridiculous. I can’t even write the name of a unit
)
