I'm installing Warhammer: Space Marine for a customer (long story, basically it would not activate on Steam, Steam support had no ideas, I'd tried everything on the Internet, and there was a good reason for a fresh install of Windows XP anyway). It comes on two discs. Only the first disc gets used during installation, then Steam has to be started, then you have to download about 8GB of data off the Internet.
I'm not sure there are many people out there with an Internet connection that rivals the speed of a DVD drive.
