Creative Adventure Disk
Creative Adventure Disk is a text adventure authoring tool for the Apple II distributed around 1986 by Select Software, a distributor of public domain software based in Sydney, Australia. Author and researcher Thomas Ferguson located a reference to the software in WorldCat and made a post about it at the EAG Blog in June 2013. A reference to adventure-building software also appeared in company ads.
The WorldCat abstract describes Creative Adventure Disk as being used to "create your own Dungeons & Dragons adventure game"; it says it's compatible with the Eamon series and is suitable as an educational aid. The system was published on four floppy diskettes.
