Werewolves are cool and all, but with all of the systems already implemented I think Super Heroes would be rad. Creating your own hero, choosing a power or two and then a climbing a skill tree that allows saving cats and stopping crimes OR causing crimes and terrorizing sims.
With the reputation, fame, and now sentiment systems they would all have varying degrees of status amongst civilians. And with different powers and possible combinations it encourages multiple playthroughs. Most occulants can be experienced in two Sims max, so this system would probably be the star of a pack than just an occ thrown into one.
