Valve has just recently announced a "Big Picture" mode for Steam for use on TV's and the PlayStation 3 to be unveiled at GDC this week.
GDC will be running throughout the week, so stay tuned for more information!
Coming off the heels of Steam's biggest year, Valve will also share with partners the data it gathered during the hugely successful launch of Steam Microtransactions late last year within its own multiplayer classic, Team Fortress 2. An in-game economy can now be readily created by partners using the microtransactions system within the Steamworks SDK."We've come to understand what type of content sells well in TF2's in-game store, and the various price points at which players value this content," said Robin Walker, game designer at Valve. "Our players are continually teaching us what works and what doesn't. Much of this feedback can be generalized to other titles on Steam, so we're looking forward to sharing what we've learned with partners at GDC. We're also interested in seeing partners get up and running with their own in-game economies, so they can collect game-specific data to inform their design decisions."
GDC will be running throughout the week, so stay tuned for more information!
