As a player in the Campaign that Los ran last year I will second everything he said. It turned out to be both a great learning experience and a very fun game. The lack of detailed knowledge on the other sides forces made all the difference. Instead of playing like a wargamer and throwing my forces away since I knew the battle ended at dinner time we had to conserve force and only spend troops when we had a chance for a decisive strike.
The key remains with the GM. Any of the tools will work but having a neutral human in the loop makes the difference in translating the output of those tools to the players.
