Breja: GOG may not share my viewpoint, but from my perspective we've grown quite enough for now this past year. Let's take a breather and figure out where we're going, rather than figure new ways to fight for more converts.
synfresh: I'm not necessarily disagreeing with you, but the point of the OP was how to you get developers to get their games on GoG without using the excuse that it's too much trouble. Like I said, GoG may be growing but it's only growing relative to the size that it once was (which was very small). The average PC gamer doesn't know who GoG is and frankly probably doesn't even care. What should concern GoG isn't that the average buyer knows who Steam is, because everyone does. It's that they know who Humble is (via Humble Bundle).
It's really interesting how many people still never heared of gog. When I saw Mini Metro was on the upcoming list, I tried to ask in the Steam discussion forum if there is a planned date for that because it is still on Early Access.
The first reply to it was "I just went to that site, what it is, a paying abandonware?". So yeah...all people know Steam and most of them are happy with that. Humble was an interesting project that helped indie, yet better known projects like World of Goo and Braid. Too bad it was successful enough that many copied the concept and sooner or later Humble changed to a Steam reseller.
Humble stood for DRM free games (Steam keys were a humble addition), now most of the games from the bundles don't even have a DRM-free version. It's a bit like an additional little Steam Sale (some bundles are quite worth the price but there are more and more bundles with games I have never heared of).
I like it when GoG grows with every game but I fear when it becomes important enough, the catalogue will be filled with very strange "games". GoodOldGames was more or less easy when the focus was solely on bringing old classics onto modern systems. Nobody would doubt I think games like Industry Giant or Warcraft 2 are classics. But with the addition of new(er) games where do we draw the line which games should be released (and who does it?). Players choice? Mechanics like Metacritic? Or is everything allowed that can possibly fill money bags?
