When a game is literally named Everything, you know you are either in for something really mind blowing or something completely devoid of meaning. But who am I to confirm that human thoughts actually have meaning? No one; that is who.
Anyhow, Everything is based on the philosophy taught by Alan Watts. It also features narration from his old recordings, some of which can be heard below in the launch trailer:
According to Wikipedia, Alan Watts' philosophy was largely based on various Eastern philosophies, such as Buddhism, Hinduism, and various Chinese philosophies.
Watts put forward a worldview, drawing on Hinduism, Chinese philosophy, pantheism or panentheism, and modern science, in which he maintains that the whole universe consists of a cosmic Self playing hide-and-seek (Lila); hiding from itself (Maya) by becoming all the living and non-living things in the universe and forgetting what it really is – the upshot being that we are all IT in disguise.
As such, Everything tries to grapple with many of the predominant themes that are present in Watts' writings. For instance, Watts proposes-- as much of eastern religion does-- that we are actually all just part of one larger whole. The grass, the bees, the bears, the rocks, the lamps, us humans too. Everything; hence the name. The game accomplishes this primarily by having you play as various things on all sorts of scales, from the microscopic to the cosmos.
Everything is available on Steam for PC & Mac for $14.99. It is also available for PS4 and Linux.
