And many people, like myself, only use Steam when forced to or when there is too good of a deal to pass up. Steam is nothing more than another DRM scam and it should be treated as such. Also, as far as requirering a constant connection, that is pure bull**** and chips.
Actualy, that's accourding to the EULA - something that is, at best, a grey issue as far as the law in concered.
Just now steam produced a popup ad for Monkey Island 3, and it keeps spawning a reminder for me to 'join the steam community' inside the friggin' game. That pissed me off so much I uninstalled it. It can work in offline mode for a while though, at least a week or so.
