Civ Mississippians. Byzantine and Vikings archetype.
Unique tech for “earth works” giving defensive bonus to castles and towers would be cool. Maybe giving all defensive buildings an artificial elevation or two. This would correspond with the huge earth mound cities built in the Mississippi River Valley.
I’d also like to see a “corn farming” unique tech that seriously boosts the farm rate. Then pair it with some high powered skirms and a good spear line their meta would be to have 100+ trash unit armies powered by their powerful farms. Giving them uber farms would be balanced by missing hussar. Then we’d have to decide if they full upgrades on their spear line etc.
It would make them sorta similar to Byzantines in that they have strong defense and trash. The idea would be some solid gold units through castle age but limited gold power units in imperial age. Their imperial age would be comprizlsed of the tomahawk warrior and trash flood. Vikings (beserk, skirm, seige late game) would be similar but viking eco spikes mid game and the Mississippian civ would have the late game eco spike.
Tomahawk warrior would be an infantry unit that runs fast and has small range like a gbeto or axeman. Though I’d like to see them both fast like a gbeto but with less range and more HP.
