Briefly want to plug the game FAR: Lone Sails, which is currently on sale on Steam for less than $4. The game takes about 2-3 hours to beat, and essentially has you driving a weird steampunk vehicle through a desolate 2D world that only renders in grayscale and shades of red.
The game is has a nice mood, and a cool soundtrack, and there is a nice balance of watching the scenery you pass as you occasionally hit the throttle or throw more fuel in the fuel tank. It's a really chill game to play in the evening after a long day, or long month in my case.
