PAW and Quill are both extremely similar in terms of their structure; at least on the Spectrum, where it’s an editor-based system. CP/M PAW and DAAD share the same DNA, and are based around source files. Uto has produced a GUI interface for making simple DAAD games, from what I can remember.
Having a system that could export to Quill on various platforms would certainly be interesting. inPAWs shows that it’s possible to do if the motivation is there. The Spanish Conversational Adventure community have been the ones driving any Quill/PAW/DAAD development historically… they produced many (many) systems based on the Quill/PAW.
There just isn’t as much interest in the Quill at the moment. We don’t even have any tools for extracting the databases from most of the Adventure Writer-variant platforms, such as the Apple ][ and Atari… Which is a shame as the Atari, in particular, has quite a few platform-exclusive games.
[As an aside, one platform that isn’t currently listed in my Quill document is an unofficial one… the TI graphical calculators The Quill Adventure Writer - ticalc.org ]
