Agree, but how will you include it? Other than your "history" tabs which are OP!  

I've got to include this someone. Pretty friggin epic, honestly.   Indeed. It's always been my thought that "darts" or "darters" meant javelins and javelinists/peltasts in these instances. I think the Kestros came a bit later, with the Macedonians, and would make for an interesting "special unit" for the Macedonians. 

I think these are better than the previous sets. Getting better and better.  May I suggest a custom tile decal for the Tachara? Like, a "Persian tile" motif. 

I made a preset functionality based on autociv's "bot" for ModernGUI

What about sea lions/walruses?
