The wider tabletop gaming system (presented in Dungeoneer, Blacksand, Allansia, Out of the Pit and Titan) was simpler than D&D but I still have my incredibly dog-eared (and in some cases very badly coloured-in) copies. These are probably quite hard to come by, and don't get much play anymore, but provided huge amounts of joy in my youth. Often we'd pace round the playground at lunch in school, telling stories and forgoing dice rolls. Good times.
