Widely accepted as the first mainstream wargame. Players are given tons of little army units to place onto the map of the world. When it's your turn, you use your units to attack other players' positions, hopefully with superior numbers. Combat is a simple dice rolling affair that stresses attrition, and reinforcements are given to players who collect sets of cards.
