I've played "wargames" since I can remember, but I have a slight issue with the idea of a "game". In combat, you can have winners and losers. The end states are easy to define and the limits can be pretty well understood. The "game" analogy works and is de-facto professional education

The issue here I suggest is with "Simulations". Simulations have limits, and as I see many limits to what "gaming" can contribute to the human and social side of the issue we call COIN.

Trying to "game COIN" might be like trying to "simulate" marriage just using an inflatable sheep. The lack of realistic responses would show up pretty quickly!
