As much as I was tired of FNAF, I thought this one was actually pretty good.
It seemed like they took everything from the previous FNAF games and bumped it up a notch. The level of creepiness was on point and the animation on the animatronics seemed to be smoother. The voice acting was fantastic, especially with Baby, and the graphics were pretty darn good. As for the story, it was kind of a hit or miss with me, for reasons im not too certain of. I liked how you weren't just in the same space the entire game, and you got to move around to different rooms and such. It was indeed kind of short, but there was a good bit of game-play there to keep someone entertained for a while. It just seemed different in a good way from the other 4 (5?) games in the series.
With all that being said, I do hope FNAF is coming to an end. It was good at first, but it has gone on for so long and become so repetitive that at this point Scott is basically just milking it for all that it is worth.
