What the OP wants is like asking Apple to provide keys for the Google Play store.

For goG's sake No, leave Gog gOgy.
Much blah blah....

do behave ladies. instead if trying for witty comparisons, go for the plunge of discussing why this would be so horrible ?

most resellers - of the shady-esque variety at least - have admitted here and there that they originally get keys from illegals sources. or at least that the users of their reseller sites probably got them illegally. but that is besides the point.

I get your argument, but how much does it really cost to have a key generated. I imagine a sort of deal could be struck where it is less then Steam's asking price at least ? also, who would buy a GoG and a Steam version of a game separately ? Is it not the point of GoG to have almost absolute freedom to do what you want with your copy?

to be clear: I am not saying that a GoG user should use his / her game and resell the Steam versions. There should be some technical limitations in place. A sort of opt-in situation during the check-out, where you only request a Steam key for example. Although considering, that you could just fart your DRM-Free copy of a game on a torrent site would essentially make the reseller argument moot ?

I think you misunderstood my point. When I said resellers I meant places like Humble and Gamersgate (that sell Steam keys) not places like G2A.

My point was as far as I'm aware Steam doesn't actually get a cut from Steam keys not sold through their own store (or at least that's how I've always had it explained to me). So it's likely nothing to do with cost.
(as for who would buy a copy of both, a hell of a lot of people on GoG would be the answer to that)

Humble used to do DRM free and Steam; look where that ended up. Hardly any bundles come with DRM free any more, it's all Steam.

If you got both versions (unless you had to link your accounts and it was automatically redeemed on Steam) then it would be very hard to stop customers selling or trading their unwanted Steam keys (which the developers and publishers don't like because it means less sales).
So GoG would probably have to offer the choice of either. But what does GoG gain from that? Of course GoG would want everyone to buy their version; one because they presumably believe their own ideals about DRM free being better, and two because even if all the interaction they need with GoG is to download the installer that is a chance they might browse the store and buy something else, or join the forum. Which lead to more sales.

Tl;dr it makes absolutely no sense from a business point of view for GoG to sell Steam keys.

Either way, I'm 100% sure it will never happen. I kinda wish it worked the other way, I'd like to port my steam games over to GOG.

If you want to play your gog game in steam, just import it into your steam library as a non-steam game.

Sorry but... it most definitely is NOT. Not even slightly!
You know why?
Because people grew accustomed to Steam. When Steam started, PC users were furious because they had to sign up ONLINE to play their single-player games! It's still kinda shitty, if you ask me.
Now all the fuzz has calmed down and that's NOT a good thing! It's like having a chain on your leg. The first few days you're angry about it but then you learn to live with it. That doesn't make it a good thing, does it?

And hey, I am a Steam user. I figured that it's okay because I usually only have games on there, which are Steam-exclusive.

However, I still value the games I have in those classic boxes on my shelves A LOT more! (All in all there should be over 500 big box games, now.) That's because nobody can ever keep me from playing them!

Origin and UPlay showed me what a hassle it can be to just PLAY a game! When games don't start correctly because their servers are down and sh*t. (I once joked with a friend that some day, Ubisoft will create "UbiCafés" in which players have to sit in order to be able to play the games they bought, so that we can't play our games at home anymore...)

I do admit that Steam really isn't that bad, compared to those services, because you only have to be online once in order to install, validate or download your game. But still: What if, for some reason, I can't access the internet and I just want to play the games (I paid money for!!)? In some cases, that won't be possible!

Regarding all that, GOG is the very best thing gamers could wish for!
If I want, I can just download my games, burn them onto CD-Rs and put those CD-Rs in my old game boxes so I can play my old classics without any problems on modern systems.

THAT'S what I want and I'm absolutely sure that's what we ALL want!

Steam might be the lesser "evil" out there, but it's still not perfect.
Not as perfect as GOG.

I remember when Steam just released. I ended up signing up and activating my Half-Life on it because the Natural Selection mod stopped making releases for any version not running Steam.

At the time, Steam was among one of the first online-connection DRM systems. And it completely devastated my computer while it was running. The entire system would freeze a second or two every ten seconds as long as the steam process was running. Kill it and it'd run just fine. Have steam running and it was useless.

What I'm saying is that while Origin and uPlay are both not good pieces of software, neither was Steam for the first bunch of years.

Steam has evolved to offering services beyond downloading your games and a server browser. Streaming, Anti-cheat, socializing, achievements, cloud saves and a bunch of other things. It has become more something you can actually find some use in having and not just as a source of nuisance to run. That's where Steam's succeeded and why Origin and uPlay struggle. The latter are just blatant DRM schemes. Steam is now accepted as more than DRM.

That said, I still buy games on Gog which I already have on Steam if they're good games. But I also buy games on Steam over Gog if they're likely to better integrate multiplayer, rapid patching (early access updates), something I'd want to play on laptop and desktop and want cloud save for. I've resisted re-buying Necrodancer here because I find I mainly play the daily run, hop in, have a go, fail and hop out. That feature is non-existent on Gog because the dev uses Steam ID to ensure you only try once. There's just some services I put up with DRM for because I can't think of a better system.

Yes, I'd rather do that discussion in the general discussion forum on Steam: I want Steam to give me GOG codes. Now that would be something: liberate all my Steam games (I have some AAA ones from bundles & discounts there) games from DRM.

But for the same reason it won't happen: it strengthens the competitor at the cost of the popularity of your own company.
