Determing Purchase Points for Map Size

[low_bidder]

Command and control makes a big difference. The player that allows his units to get spread out loses 90% of the time. Fire and maneuver. Maneuver and fire. It is better for a map to be too big then too small.
SP uses physical flags. Mostly that means you have to capture 21 hexes. Or rather you have to be holding 11 at the end of the game. Doesn't matter what size map they are on. If you are worried about your flanks, that is what scouts are for, Remember Patton's words; Make the other guy worry about his flanks. Or something like that.
