SSK is a roleplaying game. In it, you play someone with special powers above and beyond normal people, on a quest to save the world, if only because you live here. You know, the usual fantasy gaming premise found in everything from Deathtraps and Demons to Undead Superheroes: The Something-or-Other. Well, sure, maybe you're crazy. Okay, you're definitely crazy, but you might still be right. Or not. It is up to the Judge to decide, in secret, whether you're unbalanced but heroic figures like Marv in Sin City, or whether you're freaks who think they're doing right but are actually sick bastards like in Se7en. Does it even matter which one is true? Everyone has to live in their own head, and if you think you're a hero, then in your own head, you are.
