A wargame, at its heart, is a conflict simulation model. Sometimes these conflicts are historical (Twilight Struggle, COIN series, Washington’s War) and sometimes they are fictional (War of the Ring, Space Empires 4x). A great wargame will find the right level of abstraction where the conflict is accurately modeled, but rules overhead doesn’t render the game unplayable.
