When we think of existing games that could potentially be retrofit for VR, one of the first that comes to mind is Alien Isolation. There's very good reason for this. The original release of the game contained a hidden,  unofficial VR mode for the Oculus DK2 headset. Those that have tried that, have said that it's one of the scariest and most intense experiences they've ever had. Of course, previously, this was only available to gamers with a DK2. Well now, there is a mod that allows this game to played on the consumer level Oculus Rift as well as the HTC Vive. Getting the game up and running in VR isn't tremendously complicated, so if you're up for an intense horror experience, you should probably check this game out ASAP. We hope to have a review for this VR mod very shortly.
