Gray with Seleucids

Another thing I want to work on.  But my idea goes with Delenda Est's idea of the mercenary camps. I have also thought about this idea of releasing mercenary units and, in some cases, adapted special units.

It's useful to me, I must check it carefully. For now I need to fix the convert.js component has errors.   What I'm not sure about is how to call the engine that generates sound with the action. I'm still researching, there are many actions and there is no uniform way in which the actions are carried out. No action is alike. Healing isn't exactly like conversion.   What mean "pushfront"?

I had an idea that you might like: If you capture an enemy militar building, you can recruit units of that civilization as mercenary units paying with metal and you can recruit only mitilar units that your faction don´t have as mercenaries. For example, if you are using Spartans faction and you capture a iberian barrack from your enemy, you can recruit iberian swordmen from that barrack for maybe... 100 metal. . If you capture a enemy workshop from Romans, then you can recruit a balista as mercenary units for maybe... 300 metal.

Purple Persians look stylish. Red Spartans and Romans, as you've said. Blue Macedonians and Athenians. Pink Mauri. Dark Brown Seleucids. Yellow Ptolomies.
