This is simply the best puzzle game I have played in decades: innovative, challenging, and mind blowing. A true spiritual successor of MYST (but with a much more modern approach) the amount of detail and attention in the design of the island is just amazing, a perfect balance of exploration and puzzle solving. It will keep your brain occupied for several dozen hours, both during play, and the real life. There are different layers in the game and many puzzles are optional, so you don't need to do them all to finish the game, of course for a completionist the challenge is to find and solve everything ! If you like puzzle games, The Witness is a must.
