A day of Dungeons and Dragons! Books books and more books. Right now we play 3.5 edition but also have the main books for 4.0 (DM guide, Players Handbook, and Monster Manual). The illustrations are wonderful in the 4.0 books for the Monster Manual. I would suggest even if you are still playing the 3.5 edition to go ahead and pick up the 4.0 Monster Manual (unless you are the DM of course).
