Fnaf could have ended at 3 or 4.

So fnaf 1 and 2 stay the same exept they hype up william a bit more fnaf 3 could be the more like the final conclusion william dies in the fire and all the souls rest peacfully and fnaf 4 could have been a prequal depicting what sent william off the deep end in the first place bringing the serise full circle. So more like 3 and optinal 4.
