Not all. Nintendo doesn't, they just have a lot of fans requesting to make a new game.. Even Mojang and their updates. They just have to make updates to make the game more fun and enjoyable, though a lot of Android/IOS game makers seek money/attention.
Am I the only one that genuinely enjoyed playing FNAF? It was a great experience to dim the lights late at night, and see what it was all about. Frankly, it was so simple and well made that I loved it. I do hate, the fandom of it as they are all freaks, but still. Scott was extremely smart with the series with the lore, easter eggs, and he made lots of differences to each game. Also, it was amazing he could produce 3 great games in one year.
Don't you agree though that one of the reasons he keeps on making more games is for money and attention?
Oh yeah.. some of the animatronics are in front of the others or behind.. Maybe it was intentional or a little mishap.
