The Witness will always bear the honor of being one of the first PlayStation 4 games announced, and it was one of the first that I saw in intimate detail. Early PS4 buyers will still have to wait until early 2014 to play it, but according to its creator–independent developer Jonathan Blow–the game world’s sheer size will be worth that wait.
Specifically, Blow details (to the official PlayStation Blog) that his team, Vekla, Inc., has found the game takes between 25 and 40 hours to complete, depending on how thoroughly you’re exploring its enigmatic island and how swiftly you’re piecing together its secrets. Blow specifically cites that some of the game is optional, likely referencing the hidden audio logs that reveal some of the game and island’s backstory.
Jonathan Blow suspects that The Witness contains "the biggest and most-intricate world ever built for a puzzle game" and informs the PlayStation faithful that much of the location and puzzle design is finished. At this point, Vekla is texturing, polishing, and preparing the final product to land on your shiny new home console early next year.
