I was lucky enough to met the sim owner when I was wandering around , and he gave me a guided tour.
As far as Halloween sims go I was impressed with the content and detail found on this sim , from being given a flashlight to look around , to the haunted house with each room filled with a different horror/Halloween theme.
if you are looking for a place to grab pics with a Halloween theme this is definitely a sim worth visiting , you have the fog and rain effects outside the mansion , as well as various creepy characters around.
Also sound effects around the place , from squeaky doors to the squelching of spiders underfoot , a favourite of the owner is his clock with the 4 apocalypse moving around it.
Nearly forgot there is a ghost train ride where you can rezz a car and go around.
Also they are doing the pumpkin hunt , added a pic with details on.
hope my pictures give you some idea of what to expect.
