DESCRIPTION: Another World was developed by Chahi alone over a period of about two years, with help with the soundtrack from Jean-François Freitas. Chahi developed his own game engine, creating all the game's art and animations in vector form to reduce memory use, with some use of rotoscoping to help plan out character movements. Both narratively and gameplay-wise, he wanted the game to be told with little to no language or user-interface elements. The game was originally developed for the Amiga and Atari ST but has since been widely ported to other contemporary systems, including home and portable consoles and mobile devices. Chahi has since overseen release of various anniversary releases of the game.
