Do you want a complete script, retsymthenam? I'm not sure if you're objecting to these ideas because they're too high-level and you're looking moreso for unique script/gameplay, or if you genuinely want a totally novel setting and overarching plot. If it's the latter, I think most of that has already been done in terms of common parlance. If it's the former, a High level concept that's been done before (high fantasy, simple middle class day in life, etc.) can incorporate unique elements in gameplay or plotlines that other media (games/books/TV) doesn't have.
Personally, Badmanjack, I liked your plot at a high level. horror + porn can be very enticing when done correctly. Psychological horror (rather than just gore) is perfect for this genre and underdone, imo. Lots of possibility for unique gameplay mechanics, too.
