from the introduction:
As a long time RPG gamer, I’ve occasionally found the need to simulate large scale battles to work in conjunction with my fantasy games. However, there are several problems with integrating any sort of war game into your RPG:
Learning and applying a new set of mechanics mid-game can fry a player’s brain
Character death from a board game or other abstraction makes players hate you
Many wargames take several hours to play, eating an entire session or more
Some players hate this kind of stuff, as they came to play an RPG. This is often for the reasons above.
The product of some trial and error is the very simple, very streamlined FOG OF WAR – BASIC (FOG). A monkey should be able to learn it in about 5 minutes, but the details will provide enough of a challenge to keep the game interesting after several games... FOG sacrifices realism for speed of play and general balance.
