Sort of fits with canon games, I remember when I was the Outsider, kids would play a game where they would make fake bone-charms, usually out of wood or by finding stones that looked right, and use dice to assign them powers (basically, the higher the roll, the more "impressive" the power was allowed to be, so a lower roll might be something like "hounds can't smell you" or "you can jump just a little higher", whereas higher rolls could get very odd with things like being able to turn into a rat, though some were deemed too impressive and were either outright banned or requiring some drawback). Then they'd try to prove why theirs was the best (so a low roll wasn't always a loss if a kid was especially creative), usually to a designated judge or set of judges who decided a winner, though some groups would debate among themselves and choose a winner that way rather than having judges. I never participated, for obvious reasons, but it was oddly endearing and I enjoyed watching (one may or may not have given me inspiration for one of the more unusual ones seen in the Dishonored games, she rolled the lowest possible number, I think it was 2 (different groups used different numbers of dice), so hers had to have some drawback and for some reason, she decided eating white rats was the drawback, though this was before the Rat Plague so it was less "this might actually be gambling with your life" and more "eww eating rats haha"). Even little Emily played, though I don't recall any of the ones she "made". Maybe someday, I'll get a chance to play in this life even though I am an adult. Perhaps I can pitch the idea to others somehow, someday. With or without admitting that I am relaying a game others came up with in a wholly different world.
