So I had a series of dreams last night that involved the Harry Potter universe. It started with a version of me that wasn't very much like me at all at hogwarts and spun out from there. I realized that there was plenty of material there for a roleplaying game. Various schools of magic, teachers, rivals, houses, spells, and an interesting environment to set stories in. I thought about restricted or lost libraries containing powerful lore as well as forgotten rooms of mysterious purpose. Throw in Dark wizards, evil plots, the forbidden forest, the nearby town, wand creation and augmentation, classes and exams.
Then the whole thing was ruined. I realized that I would have to put in rules for qudditch.
