THQ Nordic has delivered some big time day one releases on this platform, but are there any other major publishers you could see following their example? What would it take to get them on board? The wide release of Galaxy 2.0? Impressive Cyberpunk 2077 sales numbers on GOG?

CD Projekt Red.

Forget those with their own distribution clients, but when Galaxy 2 comes out, who knows?

The AAA are too Elite to be on GOG.
Wish they would release games here but they're not so FCK them .I..

I stopped buying ps4 games because sony treats us here as third class citizens.
Namco Bandai: where the fck is soul calibur six!!??
Capcom: where the fck is monster hunter world!!??
Etc...

I'd be happy with day-2,000 for some releases.

I cannot prove this, but I would speculate that the Witcher series' continued sales numbers were largely responsible for the AAA games we have gotten through that span. So I think it is plausible that good Cyberpunk numbers would help bring another trickle of AAA games. I encourage users to buy these games any time they appear, if possible.

As for what it would take for the floodgates to open, I think that is not possible without significant change in the PC gaming market. The Scheme client holds a practical monopoly to the point people equate a release there as a "PC release" the same way they interchange "Band-Aid" and "adhesive bandage."

GOG's DRM-free stance is the main issue right?

Actually, I am not sure that is the case. I think the Scheme monopoly/monopsony issue is likely larger than that. In other words, I think even if GOG made Galaxy mandatory and the equivalent of the Scheme client, many games might still be missing from here since the "default" as it were is still to just put things on Scheme and call it a day. GOG might hypothetically have a better shot of capturing those games if they became a straight up key reseller like Humble. Of course they would lose their USP in the process, so that is (or should be) a non-starter if they are considering that kind of path.

None, outside of themselves.

^ This is exactly it. DRM-Free brings more gamers to GOG but scrapping that will lose half of GOG target audience, won't convince any of the "No Steam, No Buy" addicts to come here, and won't bring many more games to GOG if the default chronic laziness mindset amongst publishers of "Steam first, everything else an afterthought" remains the same. Humble has shown that store's that sell both DRM-Free and DRM just end up glorified Steam key resellers as time goes by. The only enticement that has shown to truly counter that inertia is the store giving publishers more money than Steam does, ie Epic's 14% cut + paid for exclusives. And if GOG followed in Epic's footsteps then expect the same "GOG are scum" shrieking and wailing currently doing the rounds from the same crowd who only support "competition" to Steam if they can ignore it.

None (minus CDPR's own games, obviously).

Almost the entirety of "AAA" (such arrogance in this self-determined definition!) games consists of awful games where "fun" has been erased in favor of "engagement" and "recurring user spending", a.k.a. not legally gambling which is totally gambling in the end. The good non-indie games are all to be found in the middle-shelf section, works like Divinity Original Sin or Senua's Sacrifice. That's why I'm happy Focus is releasing more games lately, they fit the definition of what I want perfectly.
AAAs can rot where they are.

I think AAA day one are a lost cause. I don't think there are many AA games that want to release here day one either -- although I can see them shortening the window they'd be exclusive to DRM platforms. AAA / indies are about the only games I can see being interested in day one DRM-free releases on GOG.

I certainly would love Techland, Focus Home Interactive, and THQ Nordic to release here and not too far from day one (maybe a month or two?). Oh, to dream.

AAA, in reality, refers to the publisher, not the game.

They're coming. This is why the 'One Region, One Price' thing was dropped wasn't it? Any day now :p

True, but it's really the same thing.
"AAA" as in maximum priority (like they did with newspapers pieces, more As for more prominence) or maximum quality.
Very arrogant and pretentious. Also, their games have become a blob of all features; must have combat, stealth sections, graphics, lots of crafting, expensive graphics, MMO missions... soul less trend catching.

It's been a while since big budget was synonimous of quality.

1. All games you likely like now were once AAA.

2. That last bit you wrote is subjective as all hell. I can name several good games that are AAA and decent if one gets past the "all new things are bad" hardwiring built into each new generation.
