octalot: That's the server-side part. It still needs the
client-side part for people who are using Galaxy and connecting to the server and another client-side part for people who want DRM-free games that don't need to download from the server...
Yeah, that's just the server side part which takes almost no time at all to import. The client side takes another couple of minutes, if you have the steam version with achievements already implemented, by using the steam sdk wrapper on gog which is pretty much an interpreter between steam api and gog backend. Here you go, it will save you some time if you decide to go that route

Anyway, if you want to do it the oldschool way by editing out steam api calls and replacing them with galaxy calls, it will take a day maybe for one person, but more power to you. Nowadays there simply is no excuse to skimp on features since they can easily be backported from steam. Offline gog build is pretty much the same as galaxy build, since at launch the game checks if you are logged in or not (you linked the article yourself with "IsLoggedOn()" call), i.e. galaxy features enabled or ignored. You don't have to do everything manually. Rest of it is just testing if everything works and publishing cheevos to make em visible to public.
mechmouse: Just to be clear, no one in charge of a billion dollar corporation is "Benevolent". If you remember paid mods, then you should also remember why Beth and Valve backed down the first time. It wasn't because it was a bad choice, or that consumers didn't like it, but that gamers actually cost Valve money cleaning up the support tickets
Don't bother, I've checked how well (or not) is ea and ubi doing for myself. Ea is too big to fail, but ubi seems to be sobering up a little. Maybe epic will buy it someday.
I guess it's true as some said already... when Valve is mentioned it kinda personifies into Gaben, whom I still see as a host advocating pc gaming, who fights for the users like tron, showers us with discounts with a kind smile on many an occasion. Mmm yeah, that's how I see him... portrayed in memes as Lord Gaben!
Though I agree with others that no corporation is our friend.
Btw you are the first dude I came across who didn't dislike bathesda's paid mods. There was a backlash to that on steam. Though I also remember times when we were users, not consumers who consume what is served, so ymmv.
