I'm not sure the Witness can live up to Braid, but we'll see.
The famous quote in the epilogue makes you think of an important historical event, but plausibly that's metaphorical and the game is about something more personal, existential. Maybe the game isn't about anything but making you reflect. Maybe it's an expression of particular events in Blow's life. Maybe all of the above.
He also said he responded to people who emailed him their interpretation. At the time of the interview only one person correctly guessed Blow's own interpretation.
I can't even imagine what the real answer could be.
I remember when I was originally playing the game right after it came out, and I was stumped by a puzzle and then found the "official" walkthrough and it inspired me to try my best at the game to get through it. And it really made the game way more rewarding, enjoyable, and memorable.
(The game that did that to me most often was Catherine. At least five or six times. And given that I never got very good at the puzzle version (in the arcade game in the bar), probably still at least a couple more still lurking in there if I picked it up again.)
I tried my best to enjoy it (Fez too) but I can't seem to get past the fact that they are platformers, which I have discovered I just flat-out do not like.
I actually paid for Fez, apart from its little gimmick and art work, it wasn't really much. Never finished it even, and I finished Assassins Creed 1 ;-)
Blow just seems genuinely good at writing games/software and creating puzzles, but even better at finishing.
I am not saying he Stole Fez, I am saying he seems to have mistreated people who worked on it with him. In the end, Blow is a force of nature, Fish was lucky to have someone code the engine for him, period. Look through the videos on Jai, there is some good stuff there that's not related to games in general.
Edit: Sure, it's perfectly valid to extend the meaning of "steal" to include "be inspired by" or "copy", but that does nothing but devalue its original meaning.

Blow was treated very unfairly, imo. He's actually interesting to listen to and something of a deep and critical thinker. Clearly he's someone who understands that games can be a transcendent experience like any art.
I just hope he's working on a VR game soon. I suspect the Vive is going to change everything in a couple months. I'd love to VR in the kinds of worlds he builds.
