Published by [[Incentive Software]], the ''The Graphic Adventure Creator '' (often shortened to ''GAC'') was a game creation system/programming language for adventure games.
Its main advance over the already well-established ''[[The Quill]] '' was a clever graphics editor, one of very few vector graphics editors for the CPC. This enabled 'rooms' pictures to be portrayed drawn using a minimal amount of memory.
In the heyday of the CPC, few major-label commercial games were produced using ''GAC '' (probably fewer than with ''The Quill''), but it had a vast following in the homebrew and public domain scenes - despite a comparatively high retail price of £24.95 (in the UK).
''GAC '' was also notorious for its [[Lenslok]] protection system, which mercifully was removed before the utility appeared on an a covertape included with the January 1992 issue (#76) of ''[[Amstrad Action]] covertape''.
