Firewatch is an exploration game/visual novel set in Shoshone National Park. You play a bearish guy with heartbreaking relationship problems who's decided to become a fire lookout to escape the aforementioned problems.

The park is very pretty; the narrative oscillates between Lost and Sleepless in Seattle, though not in the worst possible way. It's very short -- maybe 4 playable hours, which is a little short for $20.

The Witness is a Myst-like puzzle/exploration game with vaguely rationalist and/or humanist overtones, by the creator of Braid. All puzzles are mazes; however, there are a wide variety of maze mechanics. I managed a somewhat minimal ending condition after ten hours or so of game time.

Not recommended for the color-blind or hearing impaired. (One subsection is devoted to mazes depending on either modality, and color discrimination is needed almost throughout, particularly in the endgame.)

I recently started playing The Talos Principle. I'm just at the first "stage", so I don't know how the game evolves, but it's about a robot whose creators have been evolving for quite some times (its software is version 99, while around you can find notes from versions 10, 11, etc.), and they present themselves as Elohim.
Mechanics-wise, it bears some resemblance to Portal, where you need to manipulate objects around an environment to solve puzzles and collect tiles that allow you to progress.
The graphics is OK (cute, but not at the level of say The vanishing of Ethan Carter), and the learning curve is smooth.
I suspect it's strongly about FAI, with a role reversal (you are the AI, the humans are god). It has a very high playability and I suspect every LWer would enjoy it.
