StingingVelvet: I liked Dead Space and Dead Space 2 a lot, but mostly for the great sci-fi settings and System Shock 2 kind of stuff. Not so much the survival horror aspects, which kind of bug me honestly. I own RE4 but never finished it. Never played Silent Hill. Horror isn't really my bag unless it's mixed with another genre I love like Dead Space or Alien: Isolation.
Probably not your cup of tea then. I love those games... especially the ones that cranked the action up a bit while still maintaining a degree of survival horror mechanics.
Alien: Isolation is indeed great... that said it's really more a horror stealth game than a survival horror title. It does have a bit of survival horror, but really the goal is to never be seen.
