Should they make a larger vampire world?

Absolutely. I would love to have a 10 or 12 lot expansion map to Forgotten Hollow. It would be extra cool if it were a sort of "crossover" world to all of the Occults. It could have a swampy bay where the Merfolk come in, some dark forest cabins where Werewolves reside, and maybe a hidden lot for Aliens. Ghosts could be haunting around a graveyard and maybe it could even have a dark, mystical region for Spellcasters or even a misty Fae area for if we ever got Fairy folk. Then Occult players could use it however they wanted. If it were set up like Selvadorada but looked more like Forgotten Hollow, it would be frakking amazing.
