I brought The Witcher III - Wild Hunt On steam a few months ago, Will it ever be added to GOG connect?

Connect deals are never revealed beforehands, so we know just as much as you know.

I hope never. If someone wanted it on gog, they should've bought it here

Do you already own the base game in here ? Or you thought you can get the GotY if you connect the expansion ?

Wild Hunt is the base game.

Did gog did a thing for people who purchased Witcher on steam got a code to redeem it on GOG? I swore I heard something in that ball park when the game came out.

With 1 and 2. 3 was pretty much a no go confirmed. Most owners were people who bought it with NVIDIA graphics cards.

AH I see ok that's what it was.

I sort of agree. It was available here on launch day so if anyone really cared about having it on GOG then they could have bought it here. Still, people change their minds about things - yesterday's Steam fanatic may now be looking to 'escape' Valve's hold on their game collection.

It's possible you are right, but I think some steam buyers were hoping to get an extra GOG copy for free like with TW1 & 2. For those it made sence since they originally came with DRM, but as you also wrote, TW3 was here day 1 so anyone who wanted it could've bought it directly here.

Which is why GOG Connect, while a very nice gesture of GOG, should remain the exception and not the rule. Otherwise people will buy games in Steam and expect -or even demand- that GOG give them an extra copy. GOG needs to establish itself as a viable alternative, not as a backup website.

That being said, for some games that had been around for longer (like the first Witcher games) it probable makes sense as a stepping stone into GOG and the DRM-free world.

It's a bit odd that they don't allow it for their own franchise, is all.

Not really, it's better not to set a precedent that you can buy on Steam and get it here for free. They want people to buy it here in the first place, especially as it's their own franchise.
