Vainamoinen: Been digging through that Steam thread a bit. This is a joke, seriously. The devolopers say that
achievements and
leaderboards would be central reasons for ignoring GOG. Two abject sorry ass instant gratification mechanisms that were only created to simulate multiplayer and community where none exists and to create more generally accepted DRM (that is no less DRM in any way) out of thin air.
And with that, I assess Talos to not be on GOG because of bad game design and because of DRM.
As to the "port costs" bullshit, the game was obviously developed FOR Steam. They are finding other publishing platforms insufficient strictly because of their not-steam-ness, which is grounds to shed tears for the entire industry. All they do with their games is to support a monopoly that already killed off the central advantages of the PC game industry - market diversity and compatibility.
Amen. I was sad to read in the thread title that I shouldn't expect to see Talos on GOG. But after reading the developer's flippant comments, now I am a little bit less sad about it.
