The Legendary Guys is a quick-playing story/combat game that came as a bonus in the Level 99 Games mini-games box set. The rules are found on the front and back of a single postcard.
From the rules: "This is a short and humorous role-playing game for 2 or more players, but a group of 4 to 6 players works best. You will take on the role of the Legendary Fighters who have gathered for a duel. What you're dueling over is not important--let us call it the Orb of Ultimate Power. The important thing is that only one of you can have it."
