Bought the game on PS4. I was originally going to wait for the price to come down but after reading Jon's comments on the rampant piracy of the game, I wanted to send some love his way.
No regrets. It's an amazing looking game and very fun figuring out the puzzles. One of the first times that I had the entire family(wife and both my sons 12 and 15) all sitting around the tv and PS4 watching and playing together. My wife was even jumping in saying "oh...wait, that goes that way"! and commenting on how beautiful the game was.
