I was going to lambast some people for being idiots until I read those FAQ entries of ildon's. That does bother me some... only a tiny bit, because I have a broadband connection and don't care what kind of authentication Valve requires.
However, I am of the opinion that those FAQs are out of date, and I believe that, even if it does not happen at launch, VERY shortly after launch they will allow single player games to be played without central authentication every time you run it.
Specifically, this would cripple the gamers who go for long periods without internet access, like mobile users, people behing restrictive firewalls, or simply those who have lost their Internet connection. I would be somewhat upset if I lost my Internet connection, went to play some single player Half Life 2 to calm my nerves, and had it reject me.
I have no problem with requiring steam authentication every time I play online. None at all. Jolly good idea. But I detest the notion of requiring an Internet connection to play single player. I'd rather have CD checking.
