Surprised no one has mentioned this yet.

It's not ero, but it's still a pretty damn decent murder simulator.

The original 1980 Friday the 13th is the only film I've ever fapped to (porn or otherwise), and it's nice to be able to similarly stalk and dismember teenagers at my leisure.

I wish there were something like this with more of an emphasis on gore and maybe some ero, but it still gets away with a lot more than most mainstream video games.
