RedRabbitRun: How would you feel about some games being released on GOG with DRM *if* the publisher and store page CLEARLY STATED that all DRM would be removed, and the game FULLY playable offline, by a specific date (say, 6 months after launch)?
Yes, but I wouldn't buy the game until they fulfill their promise.
As for whether GOG "should" or "shouldn't" release such a game, up to them, their decision. I am only a customer who votes with his wallet, not a stock owner who dictates how GOG should run their business. If they feel they need to start selling games with DRM, then fine, but then I will most probably use less of my money on GOG (and gaming overall).
FrodoBaggins: I still don't see how this benefits those of us that support DRM-free.
1. Either we accept games that are infected with DRM - not good.
2. Or we have to wait X months while the DRM fans have their fun - also not good.
The third option is the worst: we don't get the game DRM-free at all.
Hence, having the game here with a delayed DRM-freeness is preferable to not having the game DRM-free at all, especially in this store which has most of my other DRM-free games and it is easy to download their installers with a web browser or alternative 3rd party downloaders.
Of course, from my point of view 2 is not really different from delaying the GOG release until the game is DRM-free. Take for example Skyrim or the Dishonored games. Look how long it took them to get their DRM-free release on GOG... but I still prefer this, to not having them here DRM-free at all, which is the third option.
