The Kushan Empire was a separate entity, more closely linked to India, and was essentially considered the leading power in Central and South Asia during its peak.

I don't quite understand what you mean, but yes, Qin Shi Huang unified China. Basically, the states mentioned were the strongest among the many vassal states of the Zhou dynasty. Essentially, the Zhou dynasty was a unified dynasty with supreme power in China, but the nobles were granted titles and land, forming their own territories, which later became vassal states. Nominally, they were loyal to the Zhou king, but gradually, central power weakened, and the vassal states grew stronger and conquered each other – that was the Warring States period. The names above are five of the seven most powerful vassal states.

Interesting, but I imagine they'll do something like Civs Perhaps for a campaign mode? I might be wrong, but isn't Qin the same person who unified China just before the Han dynasty? its maximum strength is a bit later than the year 100. That wouldn't be a problem for us, we already have pre-existing conditions.

Great, I feel that the Warring States period states of China such as Qin (秦), Chu (楚), Qi (齊), Zhao (趙), and Wei (魏) would be good choices; it was a very interesting period. Also, the Kushan Empire is also great, but the timeframe in which this power reached its maximum strength is a bit later than the year 100.

Noted but for the videos, the unit template parameters are for the "demo". The balancing of it all will be a task on it's own , my focus at the moment is to put the features out there as most of them would be optional (so disabled/absent from unit motion). It could be possible with not too much work on the code side, now that a lot of the structure is already there. But it also require a proper animation, else would look too weird. So that's for another time..  You can note that the boat receiving the blow in the video almost seems animated here but really it's just "hacked" with some rolling motion.
