The MA is a war-game. The goal, is to win enough bases of the opposing countries, to win!
Some people like the MA for what it is... hording will be a rule of thumb. That's how it is in real life, right? Lets be honest, the U.S./Allies did an awesome job with great sacrifice in WWII. But ultimately, for the win, we threw numbers at the Axis Powers.
In this GAME... there are things you can do to disrupt the horde. It's not hard, and it does take a bit of patience, but upping a horded base looking for "a fight" is not one of them.
