@CWO:
A&A is fundamentally a board game, and its relationship to more rigorous military-simulation wargames (both hobby-level and professional-grade) is roughly the relationship that the Monopoly board game has to the kinds of economic-simulation games that are detailed and accurate enough that they could be used as teaching tools in a management school curriculum.
I agree to the Monopoly comment, or maybe better said, without historical events and situations to use in conjunction with play, then A&A is just a glorified version of Risk. But, I want some history and random events that change the play of the game.
