game theory time
what if FNaF2 could be both the prequel and the sequel? There's evidence that visibly points to both cases (Faceless bonnie may mean that bonnie from FNaF 1's mask was ripped off, or he was going to be refurbished and then used in FNaF 1) and that both games represent the vicious cycle of five nights at freddy's:
there's a pizzeria with a lot of animatronics that was advanced for it's time (FNaF2)
the animatronics started thinking on their own and terrorizing the place (bite of '87 may be thrown out the window because of this but w/e)
old models roam the pizzeria at night (freddy, chica, the old crew)
the pizzeria shuts down but the old models are kept
the ceo starts a low budget version of the pizzeria (FNaF1)
it falls on hard times and shuts down
a wealthy tycoon purchases the fazbear brand
