>If you've ever played Doom, Halo, Resident Evil, Silent Hill, or Fatal Frame, or have ever watched Friday the 13th, Scream, Nightmare on Elmstreet, The Walking dead, or so much more, you have Alien to think. (sic)

While Doom started off as a Alien FPS, the others draw from other influences. ("Alone in the Dark", the largely bullshit 'true story' of the Himuro mansion, "Scream" is a lampoon of slasher movies.) While I will agree that "Alien" is an influential movie, claiming that it was the trigger point largely discredits the gaggle of horror movies that came before it.
