The first NetHack (1987): Hack plus classes, spells, fountains, thrones and a Wizard who fights back.
NetHack 1.3d (Mike Stephenson and the NetHack team, 1987) is the first NetHack: Hack 1.0.3 extended with twelve classes (Archeologist to Wizard), spellbooks and spells, prayer, fountains, thrones, polymorphing yourself, new monsters and the Wizard of Yendor, who now comes back after you. The goal is unchanged: take the Amulet of Yendor from the bottom of the dungeon and return to the surface. Death is permanent.
NetHack 1.3d is Hack with classes, magic and gods added, and the ancestor of today's NetHack. Levels are kept when you leave them, there is no town, and most items are unidentified until you use them.
