Timboli: In reality that is unknown, and Steam don't really have a say. It is all about a user's settings at Steam ... the user giving permission to share, which happens with GOG and many others, so not a GOG only thing or deal with Steam. GOG just take advantage of what Steam provide. A Steam User gives permission at Steam for their library details to be shared with a site (GOG or some other site).

As has been stated, it is all about a DEV/PUB agreeing. It doesn't happen without them.
Whether GOG compensate them or not I have no idea, but I suspect not ... or we would surely have seen more.

If GOG are compensating the DEV/PUB then they are doing the wrong thing. The DEV/PUB have already been paid ... it is a known fact ... unless of course the user got the game free at Steam ... but did Steam already compensate them.

paladin181: The system was POORLY marketed, barely thought out, and incompetently executed. The hallmarks of GOG.

Timboli: You may well be right, especially if they were silly enough to pay the DEVs/PUBs.

The way I see it though, it says a lot about all those DEVs/PUBs that weren't taking advantage of GOG Connect ... tells you what they really care about, where their ethics lie. Unhappily, that seems all of them, though maybe the PUBs are the actual culprit, rather than the DEVs, unless they are one and the same.

Ironically, I have bought quite a few DRM-Free games at Humble (either because they weren't at GOG or in some cases were cheaper than they have ever been at GOG) and was given a Steam Key as well for most of them. And I could have gifted the Steam Key to someone else. Talk about a better reverse version of GOG Connect ... shall we call it Humble Connect ... though there is no connecting ... just a key.

paladin181: I think the biggest problem with connect is it was only really ever advertised here on GOG (and on their twitter/FB) to those who already follow or use GOG. It also never had a few standing games always available (like Witcher series just for example) to entice people to come in and use it. It seemed more like a novelty that was never going to have the effect of increasing business like they hoped it would.

paladin181: The ONE place they really needed to find a way to advertise it was on Steam, on the game pages of the games that were available. And they never did.

Timboli: There would be plenty of old and new customers out there, waiting to take advantage ... just look at how often this type of thread appears.

Timbroski: This is the best summary of GOG Connect I've ever had the pleasure of reading. Props.
