People, write your horror stories of DRM here. Don't make shit up, because at least one of you will. And when I mean DRM, I don't mean swapping discs back and forth or entering a CD key, because that's copy protection, but not serious enough to be called DRM. Like Starforce/iTunes/SecuROM/DVDs/Generic DRM. Some of these might be good enough to print out to tell to my cousins. For Halloween.
OK, it seems like this thread is morphing into a DRM-sucks-and-here's-why thread. That's fine too. As long as it stays within the bounds of DRM discussion.

BioShock:
Bought the game, loaded it onto my rig, fired it up. Cool. Interesting game. Played a bit to get the feel of it, then shut it down. Did a little computer maintenance (upgraded video drivers, defragged, etc.) Played a little bit with some of the game settings.
Next day, I added a new hard drive for more storage. Fired up BioShock... locked out. WTF???
Did some googling and found out what was going on. New type of 'copy protection': limited activations and on-line activation. (After my maintenance and upgrades, I had no activations left). For months I was unable to play the game I'd paid for.
Before BioShock, I was aware of problems with Starforce games and had managed to avoid buying them. But since BioShock, I research every single game before deciding to purchase in order to find out what DRM scheme is being used. If it has SecuROM limited activations it's a no-buy. Passed on a number of games that looked interesting to me due to the DRM scheme. Once bitten and all that.

You're a brave man for admitting that. Who's next?

Back before I really knew what DRM realy was, I met it on a copy of Gothic 2, the original game not the GOthic Universe version or anything like that. I go to install the game and try to run it but the weird copy-protection scheme, which I would find out later was StarForce, either mucked up my installation OR once I did get the game installed and running would ruin my game by kicking me out of the game and demanding a CD which was ALREADY IN THE DAMN DRIVE.
That is what started the trend that I follow now where I buy the game, install game, install the crack for it and play it without hassle.
I have had more problems with StarForce than SecuROM if you can believe that.

I typically attempt to buy games without crippling DRM. But I am still using iTunes to this day because I've bought a boat load of proprietary music from them, and no longer use an iPod (my girlfriend does though).

I contracted starforce from playing Restricted Area. I didn't even know it had starforce on it until I installed and played the game. My DVD/CD rewriter combo drive died shortly after installing that game. Was working prefectly fine before so its either a coincidence that it happened to fail days after installing a starforce game or what I consider is much more likely is that damn drm killed it because it was able to burn cds and dvds.

Restricted Area was a shitty game anyways ,imho.

Yes it was, but I'm an action rpg addict always looking for his next fix after the diablo super drug.

Sacred would have worked better for you XD.

Well, the only game I installed with starforce worked like a charm and is still working to this day.
Sometimes I wonder how far the starforce evilness is exagerated. (Not telling the previous stories are fake, nor anything, any piece of software is bound to have problem, maybe I'm just lucky)

If you have a PSP check out Untold Legends, it's a brilliant Diablo-esque RPG.

The sequel to Untold Legends sucks though. They changed the perspective from sort of isometric to completely top-down...and the game just doesn't play as well in general.

Played and completed twice. Even got through it halfway with a battlemage as well because blowing stuff up was fun.
@weclock Unfortunatly I don't own a PSP, seems to be exclusive to the PSP and Playstation network which I assume is PS3, the latest Playstation I own is a PS2.

well, one that runs home brew is a great investment, IMO. I sold mine because the D pad broke, and I haven't looked back, but if I did look into it again, I'd probably actually get a GP2X but that won't play psp games.

Never had a problem with the DRM protections I encountered, even with games with activation.
When I had a pc with a broken DVD-drive (due to hardware failure) and withouth a DVD-burner I deciced to replace the broken drive with an external Plextor DVD-burner.
At some point I installed a game from some kind of DRM that also did driver modifications.
As my Plextor drive used Firewire that DRM never got activated.
All I had to do was to remove a few files or a directory from a Windows directory.
In my experience not using autorun from diskdrives helps to prevent part of the problem.
Although that only counts for audio and video disks.
