Recently I've been thinking that, with the resurgence of top down or isometric, story-driven RPGs, what I'd really like to see is something horror based. I find it odd that this genre seems to be solely stuck on fantasy or post-apocalyptic. To be honest, there's really a complete lack of good, story-driven horror in general. Recently we've had games like Call of Cthulhu and Sunken City which, for all their jank, had decent enough stories, Vampyr is kind of a horror game but not, really, and Alien Isolation, good as it was, was more a tech demo of terrifying AI than a 'good' story. Where are all our solid, in-depth horror stories?!? Things with mystery, with intrigue, with suspense? We need more of them!
If I had to guess I would assume the typically lower sales of horror games plus the typically lower sales of RPGs is a recipe for profit disaster, but that's just a guess.
Are there any other genres/styles you think are curious by their absence?
