RE2 (classic) is considered one of the best horror games from its era! Of course, nowadays it's not that creepy, anymore and not that challenging. At least not for a veteran like me. New players who never experienced this game, still should get the full experience, despite the game being old and graphically outdated.
Alien: Isolation is in my opinion the best Horror game that was ever created. It's quite lenghty (14-20 hours, depending on how "brave" you are and the difficulty you choose) Also it's stuffed to the brim with small details everywhere. Any "Alien (1)" fan with a taste for Horrorgames should give this game a chance. Beware though, the first time you might have problems with the Alien until you've learned how to handle it. At this point the game shines brightly! Wish there would be a proper sequel....
