So I researched how to get the normal ending. It's seriously an ordeal, and I don't think it will be that entertaining to watch me click random stuff on the screen and play Atari-like mini games VERY specifically. Plus, the only real difference is that the ending screen is that there are four animatronic heads, and they aren't lit up which implies (SPOILER)the children murdered that were connected to the suits are finally at rest.
Just to be clear, I'm not saying I don't like the concept. I think it's really cool how Scott hid so many things in order to earn the "happy" ending. I just don't think it will be all that entertaining for me to play, especially since I am desensitized with scares now. I mainly wanted to survive the main game like I did with the other two games, and I have done that!
