Don't forget that not everyone wants supernatural/occult content in their games. Some might be more "realism" type players, others may have religious objections (or their parents may have objections if the player is still at home). And Supernatural may have been the second worst pack of Sims3 (Showtime edges it out) because it was supernatural overload; all the occult types were watered down with the possible exception of vampires that got an upgrade over the Late Night variety. With the current trend of GPs devoted to supernaturals, it's easier for people to skip them without feeling like they're missing an entire EP, and more developer time/energy/budget can be focused on occult gameplay.
