Groucho Marx contro Frankenstein, la Mummia e il Vampiro sulla nave pirata in mezzo alla tempesta (1996)

First (and probably last) solo LARP ever. From the site of the publisher of the English edition: "From the wonderfully boot-shaped land of Italy comes the world's first Solitaire Live-Action Role-Playing Game, the most fun you will ever have alone in your bathroom with the door unlocked. Gaming (and bathrooms) will never be the same again."

This humorous pocket size booklet contains an aptitude test to properly enter in the role, followed by a full adventure built as a kind of choose-your-own-path gamebook. Combat is between the player and his image in the mirror. The player has to hit his image, which is entitled to parry the blow. If this happens three times in a row, the combat is a draw. This might lead you to think that the adventure is quite static, but you should not forget that everybody cheats in gamebooks...
