The part of the FNAF 3 description ive not actually seen talked about
Okay so to make a long story short the FNAF 3 descriptions says that the objects found have suffered *decades* of neglect and ruin. Says so right here
So this gives us something very useful, it gives us a minimum amount of time for the objects on display at Frights to have been left behind. This is not telling us the age of the objects, it spefifies that the recovered items have been neglected. Getting this out of the way to get out of the way of anyone saying it could refer to the age of the artifacts themselves
This, helpfully, gives us a minimum time for this to refer to: 1987. This is being generous, but I think that's the farthest back anything on display at Fazbear's Fright wouldve been left behind.
As I said, this gives us a minimun for the time these objects have been left to Freddy's, that being 20 years. Decades plural means cant just be ten blah blah blah. Again, this is me being generous, I think this more than likely refers to 30 years since that's the time we're actually given from the description but Im trying to be as unbiased as possible.
So, what is the point of any of this. Well it was mainly to bring up this part of the description because I dont see it talked about that much in discussions surrounding FNAF 3's timeline placement. Everything Fazbear left behind has got to be at least twenty years old. Does this mean I think it can tell us anything about FNAF 3's actual date? Unlikely! Objectively at least
I would however like to argue that it supports the read of the description referring to Freddy's as a brand closing rather than the MCI shutting down the chain in 85.
Given the description places importance on multiple decades passing twice (30 years and then this passage), I think it's fair to say they are referring to the same passage of time. That's generally how writing works. The passage of time here should refer to the same span. Obviously this is the less objective read on things and Im sure people will argue it. This is just a general dumping of my thoughts, I guess
