Matruchus: Heh, I don't undestand why people are still complaining about these things. Gog's steamlike transformation started with introduction of regional pricing two year ago, then came partial regional censorship on some games, introduction of galaxy the copy of steam client. Its a natural step if they wan't to grow as a company. I don't really see how early access on gog came as a surprise (especially since it was mentioned as an option before). The main thing is that the client is not forced for usage on single player games and that they for now remain drm-free. If those two things change then you can put a Steam sticker on the webpage of gog but not before.
Elmofongo: Personally I jus think that because of this new feature, GOG is going to focus more on adding more "In-Development" games and less on getting old classics like Command & Conquer and Total War games prior to Empire.
Or at the very least newer AAA games like Batman Arkham Asylum, Dragon Age Origins, etc.
The quality of these games can very wildly to which only a select few are good for everyone.
I mean how many people are gonna buy and play a game like this:
http://www.gog.com/game/little_inferno Compared to people that wants to get a game like this:
http://store.steampowered.com/app/4700/
http://store.steampowered.com/app/47810/
I don't really know the answer to that question but I would do anything for C&C series and whole Total War series. Not to forget Supcom which doesn't seem to be getting here out of some strange reason. It all depends on gog if it want's to rapidly expand its catalog with potentional early access sucesses/disasters or if it want's to bring more finished games here. At the end it all comes down to where they cash in the most.
