This isn't Steam related, but it does relate to the grim concern regarding DRM gaming. As you all know, D2D has "moved" to Gamefly, and by move, I mean they're dead. I meant to try Gamefly a long, long time ago, but now I, reluctantly, had a reason to finally get to doing that.
I got to keep a handful of my games, it doesn't look like I can save installers for the Oddworld games anymore, and when I was testing the install, it looked like it was activating, so saving the installed game probably wouldn't work. However, I saved all of my downloads and keys from Direct2Drive as I do with all of my digital downloads. I just have the unsettling knowledge that the only thing keeping me from having to pirate or rebuy to claim ownership is that I have a hard drive and discs in working condition, that I can never legally redownload them again. Not a nice feeling, but this is why I kept them stored, and this is why I avoided paying serious money for anything that wasn't DRM-free.
Several of my games were missing. I cannot recall, as I've already uninstalled Gamefly, but Civilization IV was definitely among them, as that's the major issue I'm having right now. I have the complete pack, and all of the keys continue to activate just fine. However, that is to say, all of the keys with the exception of Warlords. That expansion seems to use a different activation tool, which I hadn't really noticed until now, because I'm unable to activate it.
While the others use the typical securom sort of activation system, Warlords uses a "Powered by ActiveMark Technologies" system that "requires an internet connection". I'm guessing that whatever server it was supposed to connect to is now dead or invalidated. I have two choices, "Connect me to the internet" and "I am already connected". Both of them flounder about for a while, attempting to "connect [me] to the internet", and complain that I must be connected to the internet to activate my product.
I'm not sure how long it's been like this, perhaps it's been like this for a few months since it's been a while since I last installed it, but it doesn't even offer the chance to input my keys. If anybody also has Civilization IV: Warlords from Direct2Drive and would like to try and sort this out, that'd be great. Whatever you do, just don't uninstall it, or you're liable to not be able to reinstall again.
For some reason their version of X-Com Interceptor and Enforcer required activation. Their version of Civilization III was DRM-free, though, unlike GamersGate. They also had Prey, Vampire the Masquerade: Bloodlines (albeit with DRM, unlike DotEmu, but they were one of the few other places to have it nonetheless), SimCity 4 (DRM-free), Fallout 3, Morrowind, Knights of the Old Republic, Republic Commando, Dynasty Warriors 4, Borderlands GotY (GamersGate's handling of Borderlands is... odd...), and a few other noteworthy games where Direct2Drive would have been the preferable (assuming you like to avoid clients and DRM when you have a choice) or only option.
