A microgame (sometimes written "MicroGame") is a board game or wargame packaged in a small set. Microgames enjoyed popularity during the 1980s. The term generally refers to board games or wargames which were packaged and sold with instructions and maps or playing surfaces printed in a booklet format, or as one large sheet folded until it became "pocket sized" (approximately 4×7 inches). Game pieces (also known as chits or counters) were printed on one or more sheets of thick paper which the player sometimes had to cut for themselves. Other microgames had fully die-cut cardboard sheets like those included with most board wargames. Steve Jackson Games used the Pocket Box to package many of their games in this format.
