...but it doesn't prevent piracy. At all. MW2 is a Steam-required game, and I could easily pirate it right this minute and even play multiplayer. I just searched for Audiosurf (which, last I checked, was only available for download from Steam - I wanted the game but refuse to use Steam) and found a pile of torrents for the game.
Honestly, stating that Steam is mandatory to prevent piracy is laughable. It's just another DRM with a shinier coating.
Well you make some interesting points i'm not sure if that last part is entirely accurate, i have to concede what has been said that
Steam is more of a Digital Distribution Service than it is a DRM for 3rd party (non-Valve) software. (With the exception of
Valve games and of course Valve owns and developed
Steam) As i say other than the Valve games, you won't find Steam as a source of DRM on any other softwares other than those sold via Steam and digitally downloaded from Steam.
In other words; all Valve designed games are highly integrated with Steam.
Only Digitally Distributed versions of UT3 and various other games force end users to contend with Steam, a retail copy of UT3 (and other games) always either contain no DRM or a different DRM than Steam.
I view Steam as more of a DDS or CDS than a DRM, there are other DDS (Digital Distribution Services or Content Delivery Systems) such as Direct download, etc. (some publishers are implementing their own DDS) - While its a nice option; it's a mistake to think everything must go the way of DDS for publishers what about all the people with slow connections, in rural area's, no connection, etc. Even 'goofy overkill' MS realized this with an activate by telephone feature for their O/S. The entire world isn't online as much as it is assumed to be, it's not.
Which are also important key points here some not be aware of.
Bottom line:
IMO; doing away with physical copies is another 'brain-child' of the 'brain-dead' and would only hurt the industry, combine that a multitude of other headaches and you end up with a garbage product. I can't bring myself to appreciate or promote Steam for the reasons i've explained throughout this thread. (that's not saying i think i'm universally correct and anyone who has a different view is wrong - rather; it's my opinion based on my own experience and understanding) If you've bought UT3 (or other non-Valve games) via Steam and your not happy maybe buy a retail copy (or even a used copy on Amazon) next time. Unfortunately with Valve specific games it isn't possible - due to that they've lost my business, (i have a group of friends who feel the same way) for the most part unless its a must have item i do not intend to bother with future Valve games for the most part.
