Prefer playing your historical games on computer?
Well, in that case there is a first rate wargame from Talonsoft called the Operational Art of War you'll love. Along with Mark Stevens I've made a scenario covering all of WWII in Europe. In addition to allowing an historical game the players have a vast array of 'what-if' options to try out alternative strategies.
Finally I'm in the process of putting together a scenario depot for TOAW scenarios that used to have a home on The Gamers Net. Not too much there yet put I hope to be able to put together a decent library before to long.
