This information comes directly from our Facebook Group member Roberth Rivero who posts this news about a YouTuber called Manmonkee. Manmonkee talks about Discworld game, under various formats, including CD-i:

A YouTuber called Manmonkee dropped a bomb of a comment a month ago revealing something truly unexpected...It seems that Atari approached Perfect 10 Productions/Teeny Weeny Games (where Manmonkee worked) in order to port Discworld to the Jaguar CD, which never moved foward beyond the discussional phase via phone. Damn, we lost a good one...But you may be wondering what does this has to do with the CD-i? Well here's the real kicker: Manmonkee confirmed to me that the CD-i version of Discworld was not only finished but fully playable as well. So there you have it CD-i fans, you lost a good title as well 🙁

I am glad to see that our return has shaken the community!
