karnak1: Since many people have recently been accusing GOG of going back on their "DRM-free" original policy, it's good to know that a game has been rejected because it's been turned into a sort of MMO-RTS. GOG could easily have put the game for sale exclusively for the Galaxy client. But they decided to be coherent.
Alm888: One can say that this case is not an indication of
GOG's firm stance on DRM-free but is simply a matter of GOG wanting to become DRM-ed
on its own terms (i.e. to force "Galaxy DRM", not to adopt 3'rd-party Steamworks™ DRM for online multiplayer and match-making whick is most likely used in the game).
But I agree, let's hope you theory will be proven true! :-)
As I've stated several times before, if GOG ever decided to force Galaxy upon the games (i.e. becoming "Steam 2") it'd be easier for them to just close the shop instead or just sell GOG to Valve. The vast majority of users (me included) would just stop buying here and make their purchases on Steam.
Why waste time and money buying DRM'd-games here when one can buy them on a store that owns 99% of the market and offers the same services?
