I have designed a game system that is truly unique for use with non-
video games. Whether your game is with miniatures, table-top map paper
games, or a pbem (email) game like mine, my system is easily adapted.

Typical combat systems for these games see you rolling dice, sometimes
a handful of them, to see who wins. My game has no dice and no random
number generator. Results are obtained by comparing the advantages
each side has in the engagement, and choices made by players.

An advantage could be weather, terrain, larger force by type, air
support, or any from a page long table of advantages. In addition,
each player earns Command Points for victories and loses points for
defeats. As the game progresses, your points can make the difference.

The game that I am using this with is a very detailed WW2 game.
Players who are history buffs or like thinking games will enjoy the
challenge of dealing with multi-level, multi-player interaction. While
the game is relaxed, it is not casual. There are 7 Manuals in addition
to the base rules.
