Hi guys,
I've played Field of battle since the 1st edition came out. I haven't always enjoyed it but its easily my primary go to rules set for Napoleonics.
I like the rules and keep coming back to them because of the turn sequence. i find in games with strict repeating turn sequences most players tend to play the game instead of the period. they game the system to be able to increase the chances of their preferred outcome to happen more often. but the inconsistent nature of the turn sequence in Field of Battle forces players to play the period and plan in generalities instead of gaming the mechanics to their favour. Even players who didn't particularly like the system when they played did like the fact that they found themselves thinking more about tactics then rules.
contrary to some people's experience, I've found that Field of battle is extremely good at handling multiplayer games. One person(sometimes a GM or assistant GM) on each side turns the deck, and everyone gets a brigade, and acts on the cards being pulled. we've played big games on 24 foot tables with 2500 figures(16 per inf battalion, 8 cav per unit) with 20 players in finished in under 6 hours. i don't know of any other rule set that can achieve a game that big to a satisfying conclusion in that little time.
