Really

Playing the single Player mode can only be played online...sounds like DRM to me.

DRM and "piracy" are two completely different issues: the first is a technology meant to control games delivery through digital means, the latter is the industry's bullshit propaganda about how poor they are because the evil pirates out there don't feed their children.

Back in the days, manuals contained advices on how to copy the original floppies to backup a game. Now this kind of things is taboo. Filthy anti-piracy propaganda :-P

Back in the days, manuals contained symbols on pages that you later had to enter in the game to proceed. You were f'ed if you lost your manual and couldn't find the 7th letter from the 10th line. Now thankfully this kind of thing is no longer practiced.

I don't support DRM, but don't make it a "now vs then" issue. The same stuff was done back in the good old days too; just the methods might have have changed.

It's funny how question threads often have a ton of posts, but the marked solution will always be at the beginning of the first page :P

Diablo 3 was fully cracked about a month after its release. It took longer than most games (some of which are cracked before their actual release), but it is not really difficult at all to pirate it anymore. The best DRM has ever done is delay piracy, but it has never once prevented it.

Got to call bullshit on this misinformed Rubbih, clearly you are not complaining about Witcher 3, when you refer to, a "horribly buggy beta prerelease mess", you are refering to GOG Galaxy,, which I agree is a Horribly buggy mess, Beta or Prerelease, it should be, that's the problem, Steam was even worse, when at the same stage of development.

Thing is that's separate from Witcher 3 and Galaxy is an Optional client, you've chosen to use. If you was a GOG newb whose first game was Witcher 3, I would sympathise, while explaining you don't require Galaxy to play the game.

As you are clearly a regular of 3 years, You get no sympathy for your self inflicted troubles with Galaxy.
You should know you didn't have to use it, both manual and GOG downloader are available.
Apart from auto updating, I see no benefit at all for a single player game.
If you use mods, like me, the last thing you want is to auto update a modded game, so that's no reason to use Galaxy at all.

OT
As to Pirating the Witcher 3 and DRM, nothing shows the fallacy of DRM than the previous Witcher 2 release.
It was not widely known why at the time, but it was revealed earlier this year, due to almost going bankrupt, CD Projekt Red sold the US Disc Publishing rights, to enable them to finish the game.

Due to this a unique situation arose
GOG sold the digital vesion DRM free, because of course they'd do that.
The Publisher sold the Disc with DRM, because of course they'd do that.

So did Pirates steal the DRM free version, as was widely beleived?
No the cracked the DRM and stole that version, instead.

At first glance this seems stupid, but the nature of piracy is DRM is hard to crack and the accolades of the culture go to the cracking teams for making great and virus free cracks that downloaders can trust.
Reputations of quality releases are hard to get and require actually cracking the DRM, first is one badge of honour and best, is another badge of honour, getting both fo a release is the ultimate honour.

No honour is achieved by simply copying files and the users trust the named crackers, not some nameless individual who uploads the GOG version.

When no DRM exists at all, like with Witcher 3, it will still get pirated as then no Risk exists and legitimately untampered releases will quicly gain a reputation as such. Even so many more Pirates will buy CD Projekt Red games because they are anti-DRM and it's not unknown for gamers to use cracked Exe's, on legitimately owned games, simply to remove the DRM.

So it's clear where DRM never stopped pirates, for long, Like the recent Denuvo DRM, a few minor or niche games had it uncracked for a while, but as soon as Dragon Age Inquisition appeared with Denuvo, it was quickly cracked.
Also the reason Console Games aren't cracked is they don't have DRM, the console is the DRM, crack the console and you crack all games, it's called chipping the console and cracks every game. It generally takes longer as it's a hardware problem, but once done, it's done forever.

No DRM will reduce the piracy levels, at least to some extent, as some gamers will buy a DRM free game, whilst they'd just pirate all DRM games.

I beg your pardon, Diablo III was NOT cracked. And it won't be, ever, considering that the game's logic is streamed from the server to the client.

On really?

http://www.vgfaq.com/skidrow-cracks-diablo-3/

It's a combination of a crack and a server emulator that bypasses the Battle.net server connection and allows pirated copies of the game to be played offline, in single player only.

That crack is crap, and Skidrow unlocked a huge amount of absolutely nothing :-)

Just please go on and try this so called "crack" with an ISO of the game...

I don't need your sympathy; I had no problems with Galaxy and the Witcher 3 personally. But a blind man could find a post on this forum with one complaint or another. But true to the point this is less to do with the game (though it had bugs they haven't been too horrendous) and more with the less than half complete client.

Thanks for acknowledging the issues you mentioned are with Galaxy and I'm fully aware of the many posts about bugs, but actually for a game with so many users and the size and scope of the game, it's remarkably bug free.
Most gamers like me and you, only see glitch type bugs. Nothing game breaking.
Skyrim after 4 years amd thousands of bugs fixed, mostly by dedicated modders, not Bethesda, is still a buggier game than Witcher on release and we've had 6 patches in 2 months and a day 1 patch.

It still stinks when you have game breaking issues, it's not always the game though.
On the Release of Dragon Age Inquisition, Though 99.9% played fine, many people couldn't even start the game. It was an odd CTD bug that occurred semi-randomly in various points of the loading sequence, state changes, like screen swopped seemed to trigger it, but no CTD occurred in the same place, that pattern was apparent after 1000's of load attempts. 3 times I got as for as the start, furthest was the first fight, then CTD.

After three days of trying all the suggestions and reinstalling Drivers and game, Nobody affected could get it to work and consensus was it was Denuvo DRM causing the issue. All other games ran fine, so it must be Dragon Age, this was the collective wisdom
Finally, due partly to some unrelated minor issues and sheer grasping at straws, I reinstalled my pristine Windows backup. Not as traumatic for me as for others, because I run games on a dedicated Games SSD and keep all the settings outside Windows using Symbolic Links. Much better than a compolete reinstall, even so, it still needs all other Updates, Windows, Drivers and Programs.

Once Windows was back in pristine condition, Dragon age ran without issue. Something in my 6 month old windows install had obviously been corrupted, Why only Dragon Age was affected, I'll never know.
I still suspect Denuvo was the cause of the sensitivity. I posted my fix and got on with playing the game at last.

Lesson is every single day, Windows can get gradually more and more corrupted. Yet people rarely if ever reinstall it and start afresh. Reinstalling is always a hassle, even though eased with a backup. It can be made even easier, by keeping, gaming and personal, files separate and using an upto date backup.
Simply make sure that after using the backup and updating, that pristine upto date Windows becomes, the new upto date backup for next time.

If you're lucky your game will just run, if not you can be sure, it's the game at fault and not Windows or worse a combination of both.

Well no.

There's not a single crack in this universe that can fully emulate the original D3.

Read: Not.A.Single.Crack.

Never has been, and never will.
That leads to nothing. Try it yourself. A broken quests here and there, and that's with the best 'crack' ever made.

I know about D3 piracy scene thoroughly as I'm curious of Blizzard's claim back then.

(And no, I don't pirate it. I have legit copy of D3, proof: http://us.battle.net/d3/en/profile/zeroxxx-6198/hero/17289401)

No one has successfully cracked Lords of the Fallen. And many pirates will never know how fortunate they are.
