Unknown Armies/YMMV


 * Alternate Character Interpretation -- Flat-out encouraged by the writers. Every faction and character is, to some extent, open to interpretation. The GM sections of the rulebook even gives you advice for running NPCs as High Road, Middle Road, and Low Road types.
 * Harsher in Hindsight - Fly To Heaven from the sourcebook One Shots; a rip roaring adventure about plowing a passenger jet into Sears Tower  played better in 1998. Hopefully it is no longer considered Too Soon. Lampshaded in the second edition, which was released after 9/11.
 * Memetic Badass: in the game, Bruce Lee has become such a Memetic Badass that you can channel his sheer badassery through ritual magic.
 * Nightmare Fuel: The Freak is accompanied by the sound of rattling chains.
