Concept summary: A typical old-school D&D module stats list for a monster looks like this: (AC6, MV9’, HD 1, hp 4, #AT1, D1-10 by halberd). The idea is that, if it’s enough for monsters, it should be enough for PCs too. This light-rule system enables to play these modules in that way. user summary: This ultra lightweight set of rules strips the player down to the same single line of stats that monsters use.
