Tactical Studies Rules (TSR), publisher of the popular Dungeons and Dragons
role-playing game, launched its Minigame line with the release of four games in 1981.
The Minigames were about the same size as the Metagaming MicroGames but were sold
in clear plastic boxes.
These were the first microgames to include full-sized dice.
Four more Minigames were released in 1982 for a total of eight in the series.
HERITAGE
Heritage USA also jumped on the microgame bandwagon in 1981 with a series
of small boxed games.
These games were released through the Dwarfstar Games division of Heritage.
There were eight microgames released through Dwarfstar, four in 1981 and four in 1982.
