With the success of Telltale's The Walking Dead, and the increase of what I've come to call the interactive fiction genre (games like Dear Esther, To the Moon, Heavy Rain etc), we see that there is indeed a market for a narrative that puts the player in control, without the added involvement of gameplay. The merit of these games is highly subjective, but to deny their influence and the growth of this genre, would be foolhardy.
The Color Gray announces in its trailer that it is an adventure game without puzzles. Little is known aside from a very science fiction themed world and the title of the game alluding to a handful of morally grey choices that the player must make throughout. Have a look at the trailer for yourselves.
The game is slated for release sometime in August. We'll keep you posted.
