[TW: tl;dr, autism, sperging, no fun allowed]
Okay, so I haven't bought this game and I haven't played it. I don't intend to. Horror games aren't my cup of tea and I especially take issue with the premise of this game. It's so idiotic and forced I don't see how anyone can take it seriously. There are so many things that the story expects you to believe that, if any one was falsified, it would fall apart.
1) Chuck E Cheese animatronics do anything but sit behind the curtain.
2) Servos behave as described.
3) Chuck E Cheese animatronics would be allowed, expected to, and programmed to stuff the other endoskeletons into the suits.
4) They would continue to allow this if the system had even the slightest chance of fucking up and doing that to a human.
5) These animatronics are strong enough to do such a thing.
6) The programmers of these machines would not give them safety words to shut them off in the event of a mistake,
especially if mistakes were so aggressively prevalent.
7) Even if I granted
all of the above, the programmers wouldn't confine the animatronics's free roam to their room where it's safe for other people.

Even if the robots couldn't be confined to one room through programming, it wouldn't be possible to lock them into the room with a normal door.
9) Speaking of fucking doors, why are your doors space age sliding doors?
10) Why do they open when you run out of power? Why does gravity not fucking work on these heavy, solid slabs of \M/ETAL?
11) Why is it more cost effective for your company to cut power in such a way that it saves
fucking pennies and endangers lives, over not having killer robots that generate lawsuits like fucking Chuck E Cheese arcade tickets?
And probably the most fucking important question:
12) Why the FUCK do you need a fucking security gurad in a goddamn place that has KILLER ROBOTS? What the fuck is Paul Blart guarding? Killer fucking robots?
If Hitler taught us anything, it's that it's easy to convince the public of one big lie than of many small lies. If
anything mentioned above were not contrived to make this scenario work, the game would cease to exist. I'm all about escapism and suspending disbelief, but if it's so fucking forced it can't be scary. It's not something I can imagine myself doing, so I can't really be spooked.
Harry Potter works because there's such a thing as magic. The Walking Dead works because there's such a thing as zombies. Half Life 2 works because there's such a thing as aliens. FNaF
doesn't work because even if there was such a thing as killer robots it doesn't matter because everything else about the game doesn't make fucking sense.
