text: LSD: Dream Emulator is a 1998 exploration game by Asmik Ace Entertainment, released for the PlayStation. In LSD, the player explores surreal environments without any objective; they can only move and touch objects that will warp them to another setting. The game was conceived by Japanese artist Osamu Sato, who rejected the idea of games, and wanted to use the PlayStation as a medium for creating contemporary art. The game's concept is based on a dream diary kept by an Asmik Ace employee for over a decade.
  The game received a limited release in Japan, alongside a soundtrack and a book composed of excerpts from the dream diary. LSD quickly fell into obscurity, but in years since has experienced a resurgence in popularity due to its eccentricity being an engaging point of discussion for humor blogs and Let's Play commentators. The game was also released on the Japanese PlayStation Store in 2010. Critics have praised its psychedelic and whimsical qualities, with it being cited as one of the most experimental video games of all time.
