EternalSonata: NOT only that, but all of the games, from what I've seen in the Steam forums are *DRM FREE*.
Shmutt: Steam
is the DRM. I guess what you meant was there is no additional DRM on top of Steam.
Well yeah, that's what I meant. Just about everyone should be familiar with Steam's "DRM" (logging on the internet) which I don't mind since I have a cable modem that's on constantly. One thing I do dislike about Steam is the fact that you have to go Online to activate "Offline Mode", and you're pretty much screwed if you want to play something on Steam and your internet connection is down, but then again, the most popular games on Steam (Left 4 Dead, Team Fortress 2, and that little game known as Counter-Strike) are all online anyway.
Other than that, the only other thing that ticks me off is this whole crazy Euro conversion pricing thing going on and the games not even being available at all to many people outside the U.S. That's really crappy, and I feel bad for those people. =(
But still, I love the whole central location for all of your games and messaging system features it has. And Valve's Orange Box, their various weekend deals, and GoG here have completely and utterly spoiled me on buying a single PC game for $50 anymore.
