Softcover small book is in excellent condition.
The essential rules of the three boxed booklets of Original Dungeons and Dragons (1974), re-described under the terms of the WotC open game license (includes some legally required tweaks). The WhiteBox rules do not contain anything from the game's later supplements, so this is in many ways a completely different game! Adventure like it was at the very beginning! This is a complete game, very simple to master, but open-ended enough to provide a lifetime of fantasy roleplaying gaming.
