Barnight Revamp changes the barnight visitors to wear Get Famous and other costumes.
Sims will wear ghostly costumes like reaper, zombie and such. There won't be any real ghosts. I found the ghosts especially annoying in bars because they constantly cause puddles (and I'm not into occuts anyways.)

Required Packs: Get Famous, Spooky Stuff
Compatiblity: Will conflict with any mod that alters these tuning files:
