I've recently rediscovered this old game with my children, and found out what a gem it is. The beauty of it lies in the pre-game where you build up your forces and try to set traps for your opponent. I can literally see my children thinking about how to make the best placement, and even after a game, it is still going through their minds.
What a great classic game... hide your best army units and bombs in this capture the flag game, and try to out-think and out-remember your opponent's arrangement and development. It's been remade and ripped off of so many times, thanks to the simple, entertaining formula.
