Graphic Adventure Creator (often shortened to GAC) is a game creation system/programming language for adventure games published by Incentive Software, originally written on the Amstrad CPC by Sean Ellis,[1] and then ported to other platforms by, amongst others, Brendan Kelly (Spectrum),[2] Dave Kirby (BBC, Electron)[3] and "The Kid" (Malcolm Hellon) (C64).[4] The pictures in the demo adventure, Ransom, were made by Pete James and the box cover art by Pete Carter.
GAC had a more advanced parser than The Quill, allowing commands like GET THE LAMP THEN LIGHT IT, and a built-in graphics editor. Over 300 titles were written using GAC.[10] It also came with a built in text compressor.[5]
