Via Anders Sandberg, here’s Tobias Radesäter’s Supergänget, a Swedish superhero roleplaying game entirely in comics form, reminiscent of Scott McCloud‘s Understanding Comics. As the players switch to their superheroic secret identities, the GM changes into his secret identity of game designer, and takes the reader on a fourth-wall-breaching guided tour of the game, including a visit to a jungle of system-monkeys and a combat-section dojo. All of this is done very nicely with the bright color and clean line of the Euro-comic.
And (if you continue to the last page), you discover that the Swedish equivalent of “The End” is “Slut”.
