amazing! but are you taking requests for any additional knights?
Id personally like to see the late era knight again, but with the civ colour as the dominant colour. Id really like to use it as a 'royal champion' unit, that would be automatically produced every so often by a 'royal court' small wonder, in addition to any 'normal' knights that you build. But with two all-red knights going at each other, it would look a bit wierd IMO... or at least not the romantic image of the elite kngihts fighting for the honour of their colours...
anyway great work, and i appreciate that there are problems with the civ specific colour.
