Yeah. They have the security room, the stuff you see on camera feeds, and the animatronics / jump scares to design, and that's about it. Not that I'm saying that's a bad thing, but the Five Nights at Freddy's games are very simple in their designs. They're really more about the story and scaring the shit out of you than graphics or gameplay.
I'm more of an Amnesia fan myself (it's one of the few games that actually has made me jump a time or two), but I love games like that.
