In The Witness there are orange-coloured audiologs underground. They often feature dialogue or monologue by what seems to be the game's developers. Are these actual recordings of the development process that they put in, or was this all also scripted and acted out? I tried searching the Internet, but could not find anything. Have the authors ever commented on this?
Added: I'm not really interested in fan speculations. The game is deliberately very ambiguous so there's bound to be lots of those in all directions. I'm wondering what the makers of the game themselves have said.
And if they haven't, then if there is some fan speculation that makes such a strong case that it has become the prevailing opinion in the community, I'll take that too.
Otherwise we can just leave it as "ambiguous", which is, I think, the best word to describe the entire game. :)
