From OD&D and its various supplements, to BECMI, to Rules Cyclopedia, to AD&D, 2nd, 3.0, 3.5, to whatever editions I have missed? EVERYTHING IN THEIR ORIGINAL FORMAT, NO EDITING. By core rules i mean Monster Manual, DMG, PHB, as well as all the original contents of the boxed sets, and just or nostalgia sake, all the OD&D books, . Would you want to see WOTC put them out again?
