I definitely had rogue legacy in mind! Great game, but I don't think it leaned hard enough into just how grim and manipulative the whole enterprise is. Also I think you could have a lot of fun with the "marketing" mechanics, like, can the fairies explore the "real" world at all to find the right place to leave their macguffins? Can they leave better "bait", like magical books for the chosen kids to find, or even a shiny sword where it doesn't belong? Maybe they can recruit agents in the real world whose only job is to guide kids into their meat grinder.
