I like it
I like the upgrade options, I like how archers are as important as they should be but you are actually given the control you need.
The ground is always flat which provides little variation. Enemies always seem to have the same AI which makes gameplay less challenging. I think the delay on centaurs and humans is too short, I found it rather easy for most of the game since I always had my humans and centaurs. Flag guard upgrades were unnecessary, since they were nearly always behind my other units.
It's nice, it's rather simple, but gets repetitive.
