Nice.... and creepy looking. I know very little about Silent Hill games, although I have seen just 1 movie - which took me three times of seeing it to see the whole thing. It is very creepy and I tend to watch movies by myself as my hubby is not a horror fan. The little girl vanishing from the car is what intrigued me to watch the thing to begin with... hehehe. So I cannot be a real good judge of accuracy or anything else as I was a bit horrified (and at times grossed out) through all three experiences to judge - but I do know I like what I see and REALLY love your sims. Hope they come with the world. But yeah - looks like a really great job at recreating an creepy environment and should be a good world to play.
I do hope the fog factor holds up, as I am not sure if you noticed, but Seasons messed up the Ambitions fog effects so they no longer show in worlds made using them. Rflong - who uses those effects a lot had to use SuperCaw and hand place each affect to even get some of them to show. Just thought you may need to be aware of that if you were not aware before.
But anyway, great job.
