‘ABC’ is a one-page generic role-playing system for games masters and players who prefer improvisation and minimal rules.
It is designed to be easy to remember (the mnemonic for character creation and challenges is as simple as 'ABC').
Written by C.J. Gledhill, with material and mechanics inspired by S. J. Ross’s "Risus" as well as "The One Ring", "Trail of Chulhu", "Traveller", "Tunnels & Trolls" and many other great RPGs beginning with "T".
