Crusader Kings 2 and Fallen Enchantress (I know about CK2 on GG)

I've also increasingly had my enthusiasm for console gaming tempered by the fact that more and more games are requiring 3rd party activation / account registration / content locking and have several publishers on the "will no longer buy" list because of it. It really is a letdown and I hope companies start to reverse their course.

I NEVER buy any sort of game with DRM.
I never installed STEAM and I don't intend to. I don't want no software to decide how I play or how many copies of the game I can have.

When I buy a game it's supposed that I should be the sole owner of the software. When I buy from GOG I get the full game from GOG.
When I buy from "Stink" (STEAM), or any other DRM client I'm only borrrowing the game from them.

DRM? No, thanks.

EVER!

I'd rather have a pirated game than one with DRM.

I don't allow any DRM on my system at all. If there is a CD check on a physical disc of an older game (I don't buy boxed games anymore nor anything with DRM) I'll run a fixed exe.

Every Ubisoft game. Granted, I wouldn't have bought many of them regardless, but I've had such terrible experiences with Ubisoft and DRM in the past that I flat out refuse to buy anything off them these days. This includes DRM-free games.

Every EA game with Origin, but I have resented EA for a long time and probably would not have bought any of their games even if they were available DRM-free: it's just that the possible need for Origin makes me steer clearer still.

Quite a lot actually and many titles I would really have loved to play.

Super Street Fighter IV - Arcade Edition
Fallout - New Vegas
Diablo 3
Starcraft 2
Skyrim
Mafia 2
Bioshock 1+2
Portal
Half-Life 2 (The later versions in Germany forced you to Steam...)
Injustice - Gods Among Us (aaaaaarrrrgh, I always wanted a proper DC Beat'em'Up for PC)
Magicka

Vote with your wallet!
It was particularly hard with these for me, but I did it...

Anything on steam that has more than steamworks on top of it. Absolutely hate drm on top of drm schemes. It's like a matryoshka

Disk in the drive was never DRM. "copy protection" yes. Stupid yes, but not DRM. DRM is them revoking your ability to use the product unilaterally, through no action or inaction of your own.

Anyway, on topic. TONS! Some of them being:
Starcraft 2, Diablo 3, Torchlight 2, Deus Ex HR, Duke Nukem Forever (yeah, I know...), SimCity, Spore, Civilization 5, Team Fortress Classic, Bloodbowl (and others by Cyanide Studios), Dead Rising 2+, C&C 3+, Darkspore, Elemental: War of Magic, GalCiv 2+, Magicka (and a ton of over games by Paradox), Faery Legends of Avalon, Hoards, Skyrim, Majesty 2, Borderlands...

I used to keep an active list, until DRM got so bad that nearly every new release made was put onto it.

The ones that ALMOST made me pirate for the first time in over a decade were Civ5 and Torchlight2, but I held strong and have done without.

Special note: I'd preordered Cities XL back when. Then when they released it with DRM later, they refused to refund my preorder. Fortunately, my bank reversed the charge.

Forget the DRM, I've had trouble with Ubisoft and getting the game to work period! :P Now I don't want that to stand as a blanket statement on their entire catalogue; I'm sure they have many fine titles that aren't bugged to hell and back.

I've never come across one, but I'm sure they exist.

Mass Effect 3 and Diablo 3. Although my friends who played them were very disappointed, so I guess I didn't miss out on too much.

Hmm...

Never bought, played:
Simcity
Dark Souls
Skyrim
Bioshock 2 + Bioshock Infinite DLCs
Dishonored
Lost Horizon

Played but haven't bought digitally:
Gray Matter
Black Mirror

There is probably a couple of more but I don't DRM prevent me from buying. I just wait for it to cost cheap if I haven't played its CD mag copy or by different means (not doing that anymore). Then there is the factor of "how big are chances the game will be ever without DRM".

And then there are these games that were supposed to be released DRM-free however ended up being DRM on Day 1 and my enthusiasm to buy it full price cooled down which led me to waiting for an eventual discounted DRM-free version. That's something I wouldn't describe as a game I haven't bought because of DRM since they are usually already DRM-free.

Indeed, that shouldn't even be legal. I believe the newly released M&M X Legacy requires uPlay even if you bought it at Steam and upcoming Watch Dogs will require the same (just like Splinter Cell Conviction did and still do).

Not a whole lot of games. Diablo 3 & the new Sim City are two. I generally try to avoid anything that requires me to be constantly online while playing or which has limited activations.

All this DRM stuff with the big players has strenghtend my retrogaming needs and drove me into Indie gaming and I should be thankful for that. :)
There is always an upside, although I HATE to have to pass on a Fallout game...
I bought the DRM free Fallout games twice each (German and original version) and never touched New Vegas, because I'm not into Piracy.

everything thats not on steam. (like mass effect 2, dragon age 2, sim city, fifa14, nhl09, ...)
everything that depends on a server component for the game (not just drm).

with the sole exception of blizzard battle.net titles... (those i just play too much and only online so i don't care)

i do mind drm but given steam's vast catalog & rock bottom sale pricing i probably spent as much $ there than on gog... but then thats for about 5-times the games... so about $2 per steam game :)

is that i find & test a nocd/steam fix to all non-gog games... so i can play when & where i want. oh and i don't buy anything on steam before there exists such a fix...

the simple truth of the matter is that because of the extra work i have to do for steam games they simply have less value than gog's...

Crysis, Spore, lots of EA games actually, Shogun 2 Total War, Men of War: Vietnam, Napoleon Total War, Fallout 3 (I wanted to at least give it a try), Deus Ex: Human Revolution, Metro 2033, Battlefield 2142, Kingdoms of Amalur, Wolfenstein (not sure about this one), (until recently) Risen, Dragon Age: Origins (like with Risen, thought it would be better on PC. I don't think my opinion is about to change), games on Steam, and probably lots more.

Just thought of Vampire the Masquerade: Bloodlines (or at least because it is not here).
