Yet, I can't deny that those books are unnecessarily ponderous. Even though I used most of its rules back in the day, I'm not sure much was gained with the added complexity of AD&D and I know much was lost, in particular the free-wheeling, open-ended nature of OD&D. Part of the appeal of games like Swords & Wizardry and Labyrinth Lord is that they're so compendious, a virtue long since bred out of the descendants of OD&D.
