My husband wants me accompany him while he's playing "Vampire, The Masquerade". He said that he's scared as he needs to go into a haunted house to get something. So I sat beside him and he was scared that he sat quite far from the computer with arms stretched out.
For his safety, don't let him play Amnesia : The Dark Decent or any of the Silent Hill series. If Vampire Masquerade is scaring him then those might be dangerous to play.
I don't blame him. I made the mistake of playing that level with the lights turned off. I don't think I'll ever be able to wash the stains off my pants.
