When depicting “military” events, I spent a lot of time digging through journal papers and found little published evidence for “armies” as we think of them now.
Supposition: A village of 250 people has perhaps 1-5 “warriors” (people who are able to dedicate themselves or martial pursuits. The remaining “warrior” are just the villagers. This would make inter-tribal warfare very dangerous as a destabilization factor in a village. An unsuccessful raid would literally damage your own villages’s ability to make food, an opportunity cost.
As I recall (sorry, cannot remember the source so call it supposition lol) there is debate over just how deadly most early warfare was. In effect, I have heard it argued that “battles” could have been somewhat ritualized in some cases. It’s been ten years since I researched that specific topic… sorry for weasel words.
As for the dance areas, neat! I hope that turns out to be well supported as I am more interested in the cultural arts of the time than the battles.
I very much hope some rituals, celebrations, etc are added to the game, not just battles battles and more battles.
