Just watched the Digital Foundry video and yeah this does look like a pretty nice remaster so there's that at least, still I'd prefer if they kept the original. Nightdive is also weirdly inconsistent with preserving the original releases, Blood Fresh Supply comes bundled with One Unit Whole Blood on GOG but doesn't include the original in any way in the Steam version, Strife has the original and even a beta version included as a launch option on Steam and System Shock Enhanced Edition includes the original as a separate library entry while Turok or Shadow Man's original versions are just gone and I think it's safe to assume that's what's gonna happen with SiN and Kingpin as well. I'd like to at least just know based on what exactly do they make these decisions.

Both options are also available in the GOG version of Strife and the old version of Turok was never digitally available anywhere before the remaster from Nightdive was released.

Did I miss some information in this thread about GOG having control over the publishing of this release? Afaik it's up to the publisher whether or not a game stays up.

(besides "Good Old Games" not being their name anymore)

You can still get a Steam key for Shadow Man from Humble Bundle.
