I explored that idea, but frankly, it’s difficult, if not impossible, to implement without also having 2-pop villagers as a baseline for the civ.
While that’s not a bad direction, it means that the civ would ultimately only need to achieve about 45-50 villagers to be on-par with other civs, which could be reached at an absurd speed due to the Lakota need to hunt at an incredible rate.
The villagers would need to cost something like 225 food apiece just to balance it.
It could be done, and frankly, I don’t think there’s a better civ to explore the concept with than with the Lakota, but it would be hard - it would, incidentally, coincide very well with my concept of the unique Lakota villager, the Khuwa, which is intended to inherently have a higher attack, hunting rate, and wood gather rate, but a less-than-ideal gather rate from buildings.
SO… it could be done, but it would require a lot of fine-tuning, and I don’t know if the devs want to put the effort in. Would it be cool? Hell yeah! I’d love to see it. But it would be hard.
ADD: This might also be a point where a unique Dakota villager could be available, the Wozu, that would be more like a normal villager, not mounted, and specialize in gathering from the Three Sisters Garden. Sort of like a reverse Settler Wagon, it’d be a weaker villager available that’s more cost-efficient on the Garden than the Khuwa are.
2nd ADD: The Wozu could also be available to the Hauds, interestingly. The Dakota and Hauds would not have been far from each other, with the easternmost territory of the Dakota being within a few hundred miles of the westernmost Haudenosaunee borders. It could be similar to a Mercenary Villager or Native Villager that both can ship in that specifically gathers from the Three Sisters Garden faster than either of them.
Would also make sense, as the Dakota were remarkably proficient at the method, to a level that most other woodland natives were not.
(Wozu means “farmer,” while Khuwa means “hunter”)
