Another World, also known as Out of This World in North America and Outer World (アウターワールド Autā Wārudo?) in Japan, is a 1991 cinematic platformer action-adventure game designed by Éric Chahi for Delphine Software. The game tells a story of Lester, a young scientist who, as a result of an experiment gone wrong, finds himself in a dangerous alien world where he is forced to fight for his survival. Originally developed for the Amiga and Atari ST and later released for the Apple IIGS and DOS platforms, the game was widely ported to other contemporary systems. Later efforts resulted in several game engine recreations for the game that permitted it to run on modern computers, consoles and mobile phones. In 2006, Chahi independently released a 15th Anniversary Edition for modern computers, and a subsequent 20th Anniversary Edition five years later that adapted the game for numerous consoles and mobile computing platforms. Another World was highly innovative in its use of cinematic effects in both real-time and cutscenes, which earned the game praise amongst critics and commercial success. It also influenced a number of other video games and designers.
