Snickersnack: I thought Mumbo Jumbo was formed by ex Ritual people. Why would they obstruct a SiN release on GOG? I'd have expected some sentimentality on their part.
MumboJumbo was formed by some Ritual devs, but they
bought them a few years later. See
here and
here. I remember reading somewhere that since SiN Episodes 1 was a sales failure, they didn't authorize any sequels.
grviper: Weren't all re-releases of Sin censored in terms of other game references?
The Steam version was. There are still some unpatched retail versions that were shipped with the unchanged contents, but updating the game with the final patch removes all that, I believe.
