So, I've recently watched gameplay from that game Strategos and I really admire their "messenger" mechanic. For those that haven't seen the game, it simulates the lack of real-time communication in battles, so if units are a certain distance away from any "commanding" units like generals, they will not follow orders instantly. Instead, giving an order will cause a "courier" unit (a single guy on a horse) to depart the General's unit formation and run to the unit in question, relay the message and run back.

You're limited to a X number of couriers per General unit, and until they've returned you can't send further orders. And couriers can be intercepted by the enemy (but you can also intercept their own couriers) voiding that sexy flanking maneuver that was about to happen.

I wonder how feasible would such a mod be? This looks like it could be an awesome thing, and while Strategos is definitely fun by itself, I'd love to play a more "complete" (and realistic looking) game with that mechanic!
