Wizards of the Coast, the company that now owns the Dungeons and Dragons brand, is releasing PDF versions of classic manuals and adventure modules. The thing is, the early versions were often flawed, sometimes deeply. Still, nostalgia will likely trump the flaws, and it's not like you couldn't have fun with the old stuff. Far from it. And it would seem my old manuals may actually be worth something nowadays, even as chewed up as they are.
