The Tech Report - Cheating on my CDs and DVDs with Steam.
From a gamer's perspective, Steam seems to offer the best blend of social features, cloud storage, automatic updates, and ease of use of any current distribution system. I'd like to see Valve work to integrate other commonly used third-party gamer tools into the package. For instance, the ability to merge my Xfire friends list and chat capabilities with Steam would be great. This would eliminate having to maintain duplicate lists and manage multiple IM programs.

Fragmentation worries me, as well. If every game studio decides it wants a piece of the pie, how many of these delivery platforms will we have to put up with? I'm certainly a proponent of healthy competition, but the danger of alienating gamers with too many sales channels and social networks is something that aspiring services need to consider.
