"Go" was an Italian-exclusive regional release produced by CapDisc in 1992 and according to various release lists it was due to be released in other languages as well. Somehow, this didn't happen but Oldergames picked up the CD-i prototype of the english version and released it in 2002 as a CDR to the public. This game is fully playable. Below you will see the original italian release by CapDisc:
The Internet doesn't give away many details about the back cover and the inlay, so when we see some pictures showing these, we want to preserve them for the CD-i community. The pictures below are posted by CD-i member Simon Williams, many thanks for sharing!
