DRM that works. Have you seen the alternatives, complete with install limits?
Yes, it is bad. Games such as Spore go a really wrong route by letting you install only 3 or 5 times.
Offline mode

. But seriously I don't have an internet connection at my place abroad. Infact my Macbooks L4D and TF2 weren't updated for 6 months yet they played just fine in offline mode (well L4D and the HL games did, didn't even try TF2 for obvious reasons). If it's never connected it doesn't know theres an update to pull down.
Unfortunately for offline mode to work you need to connect to Steam initially and then switch to offline mode. (Completely defeating the purpose of online mode IMO). Here is straight from Steams website:
Please note that you must connect to the Steam Network and test each of the games you would like to use in Offline Mode at least once to set up your account and configure Offline Mode on your machine.
Unfortunately they are right. I am unable to install Orange Box because of it wanting to update first. (Then it tells me that its not valid anyway).
That's very odd. You need to prove to Valve you bought it, provide them with a reciept or something. I had the same thing happen to me when one of my accounts was stolen. I got it all back with no problem.
I tried that route. I even sent them the box pictures and the receipt from Best Buy. They told me I must be mistaken and have someone elses game.
You're admitting to pirating Steam games?
I knew someone who pirated L4D. Because you can't connect to the Steam server he was limited to Single Player only which is no way to enjoy the game. I've put hundreds of £ into Steam over the years, which would have cost much more if I bought elsewhere

.
I admit I have a "suspect copy" of Orange Box that I bought it in a foreign country for $2 and unlike my $40, my $2 version works without having to update or anything.
I am completely against software piracy and am the only person I know who owns legit copies of Adobe Master Collection, Maya, ZBrush, Corel Painter, etc. But, I'm also not about to get ripped off by an incompetent company with incompetent tech support people who, after having all the proof in the world staring them in the face continue to tell me the product I bought (and that worked) is invalid. Sorry Valve for buying your game, I wont do it again as long as you have Steam requirements.
I stopped buying anything that has Steam in it (Borderlands) because I know it will be impossible to play until I get home.
And no, I do not pirate. Orange Box was the only exception because I already bought it.
