ShadowOwl: The game was on Steam in the past:

I don't see why it shouldn't return to Steam in the near future.
I have been thinking about this and I've come up with a speculative theory.
Maybe the reason why GOG got an exclusive (for now at least) on the butchered version of Mafia is because the butchered version was offered to Steam first and they passed on it.
Why would Steam pass? Because they don't want to tick off all of their customers who have bought the original/non-butchered version.
Steam only features
one version of any one specific game on its platform, right? So if they did accept the butchered version of Mafia, how would that work in light of them having released the non-butchered version previously? Are they going to release a new patch that is forced onto all of their customers who have the original/non-butchered version, which ruins their versions by debasing them into the new & butchered version?
Maybe selling the new version on Steam could work if they called it something else to differentiate it from the original, like "Mafia: Gimped Edition"...but apparently the publisher and/or Steam doesn't want to do that.
IMO it
should be called something else (other than "Mafia") on GOG, because the version of the game that they are selling is a new & worse game that is not the same game as the original, but to call both versions by the name misleadingly implies that they are equally the same game.
