I would play on VASSAL but my older laptop seems to grind to a halt for the two Vassal modules I have tried. I tried the Twilight Struggle and Hornet Leader 2 they worked but were very jerky. I might have to find some opponents. Anyone up for a game week after next ;)!
Download the updated Vassal and Combat Commander modules. Tim has stripped out all of the auto calculations that were resource hogs.
