Query: Wellington Rules

I highly recommend this rule system. I have used it to run games at both Conventions and for out local gaming group. Players pick it up quickly, it has a good Napoleonic "feel" but without long flowcharts or a vast number of "situational" rules. A resonably sized game can be played in 4-6 hours. A good companion to "Santa Anna Rules" for the Mexican-American War.
