The Unfinished Swan came out for the PlayStation 3 several years ago but I only recently got it on the PS4 and boy is it a unique and satisfying experience. You control a child who has a magic paintbrush and you make the scenery come alive by throwing splashes of black paint around. This creates a stunning visual experience as the world appears in front of you slowly. I loved this short 2 hour experience and think that there is definitely space for video games like this in the gaming landscape.
Check out some of my screenshots.
