Abzu
Your enjoyment of Abzu will rely almost entirely on the game's aesthetic. While the gameplay is quite soothing, it is as simple as it gets (swim, then swim more). Its narrative (if you can call it that) is almost non-existent. But if you're okay getting lost at sea for two or three hours with some of the most beautiful art and some of the most pleasant orchestral sounds that the PS4 has to offer, then this is a no-brainer. There's even a "meditate" mechanic if you'd like to stay lost for a bit longer. As a pure "video game," there really isn't much here. That being said, it was the most soothing, relaxing, pleasant experience I've had on a console since Flower.
