Ah, sorry, I thought you intended to focus only on the QIE games.
I'm more than happy that you noticed the common backstory and that you appreciate it! It's purely ornamental, but I found it fun to connect totally unrelated games in such a weird way. At some point I stopped as I could no longer afford to update the manuals (especially those formatted for printing, where changes can be painful or even impossible) of the past games and re-package and re-release the latter every time I added a new game to the "saga".
