In the nascent Computer Gaming scene of the early 1980s, Text based adventures were a formidable presence on the shelves of game stores. The likes of ‘The Hobbit‘ and ‘The Hitch-Hikers Guide To The Galaxy‘ were fine examples of interactive computer-based fiction, taking the limitations of the Hardware and operating Systems they were written for and immersing players in new worlds. If you want to play any of them, have a look here;

Within a few years of Adventure Games becoming a staple of home computer gaming, an affordable utility was released on several formats that gave the average gamer the opportunity to become a producer of Adventure Games. That utility was The Graphic Adventure Creator, aka GAC:
The Graphic Adventure Creator
The Graphic Adventure Creator (aka GAC) was a game creation system/programming language for text and static picture adventure games, published by Incentive Software, and retailing for around 20 pounds (sterling) at the time of its release (1985 / 1986). It was unusual in that it was originally written on the Amstrad CPC by Sean Ellis, and then it was ported to other platforms (such as the Sinclair Spectrum, Commodore 64 and BBC Electron). There were other adventure writing utilities available, most notably The Quill, but GAC was multi-format.
In a bid to try and stop the copying of the utility, GAC had a unique security device called the lenslok, which was essentially a plastic viewing receptacle that allowed the user to decode scrambled pixels into ascii characters. However, the lenslok, that shipped with very few games, was not without its problems, as reported in Crash
Lenslok Instruction page (included with GAC)
Once you got past the security, you were into the utility itself, and could begin creating your very own text adventure. The TUI (text user interface) was fairly intuitive for its time, and you could quite quickly create an adventure with several scenes and actions to undertake;
I tried to create a post-apocalyptic epic. I say ‘tried’ because to create a truly worthy adventure you needed the time, planning and patience that I obviously didn’t have. GAC was duly abandoned by me within a few months of several aborted attempts in favour of the likes of indie music, girls and eventually, when i returned to gaming, the Sega Master System as I abandoned my CPC464 and home computer gaming forever.
GAC was a unique and brave attempt to put the power of producing games in the hands of the average user. The aptly names Incentive Software also gave fans an….incentive by offering to publish those games produced with GAC that were, in their opinion commercially viable. I seem to recall some of the computer gaming magazines at the time running GAC competitions, but no hard evidence. Can anyone out there who reads this remember if there were such competitions, what the prizes were etc?
At the World of Spectrum site entry for GAC, there is a list of all the adventures created and published with the tool;
