Honest Opinion, Its Sister location that scared me the most, specifically Funtime Foxy's part. its Unsettling for me to Flash a light every few seconds to see a Giant Pink and white fox rapidly approaching you
Unpopular opinion: TheVR games, because you don't realize how huge the animatronics actually are until you see them towering over you, moving around on the cameras and in front of you. Especially the FNAF 2 section where they're literally in the office with you. Also Toy Freddy merging will Withered Freddy is unintentional nightmare fuel.
