. . . wherein Paul Gorman plays with ideas for old-school fantasy roleplaying games
UPDATE: the beta version is now available.
Paul, you said in your post linked above "I hope someone releases a close clone of the 1974 rules." Having a look at your pdf and given the goal you had set yourself, I reckon you'll be very happy with the soon to be released Delving Deeper clone of the 3LBs by Brave Halfling Publishing, which sets out to do exactly what you wanted to achieve. Thanks for releasing your file, it's encouraging to see someone with the same vision that we in the BHP team have for the original game.
I'm looking forward to the BHP clone. I placed my Delving Deeper pre-order soon after it was announced.
