LSD

LSD: Dream Emulator is a 1998 exploration-adventure game by Asmik Ace Entertainment, released for the PlayStation. In LSD, the player explores surreal environments without any objective. If they touch anything in the environment, such as walls, creatures or objects, they will be warped 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.
