Valve Software's celebrating the official launch of TV-based "Big Picture Mode" today, which enables Steam users to play PC games on their televisions with a user interface designed around the experience. As a result of the celebration, "over thirty" games are seeing prices slashed by as much as 75 percent through December 10th -- those games, as you might expect, are geared toward controller-based gamers. Should you wish to get in on the Big Picture phenomenon now that it's out of beta, all you've gotta do is sign into Steam with a PC or Mac connected to your television and click the "Enable Big Picture Mode" icon in the upper right hand corner. Not sure if it's for you? Take a gander at our hands-on from back in September to get an idea of how the service stacks up.
