If you're looking for horror video games that aren't too overwhelmingly terrifying that you'll wet the bed, game devs have definitely made some titles that fit the bill. There are plenty of good horror video games out there that are as creepy and scary as they are underwhelming. These aren't titles known for being the best psychological horror or survival horror games, but they'll definitely keep you on the edge of your seat.
For your casual frightful gaming pleasure, studios of all sorts have come together to bring you a collection of scary video games that are good, but not great. They're not Silent Hill, they're no Five Nights at Freddy's, and they're certainly nowhere near Eternal Darkness or Amnesia: Dark Descent, but they're still pretty decent horror games that will give you a thrill to pass the time. Vote up the games that you find pleasantly entertaining with a good enough scare.
