One of the things that I love about Crimson Butterfly is being able to explore/run around the whole village, something I wish they'd repeated in the FF3 and 4 but since those games were set in more confined locations then I can hope that should there be a 5th game that this time it will be a more open area. That said, something I had watched years ago as a perfect setting. Aokigahara, a suicide forest in Japan, I have to say I feel like a crappy person taking a tragic location and wanting to make a game out of it! Game or not I love and am fascinated by it's history and mystery. As far as a game goes it would be a good setting I think, it's has history, truth, emotion, and certainly is a spooky environment.
