Steam Big Picture Mode released, offers celebratory sale

Valve has brought Steam's Big Picture mode out of beta at last, and to celebrate, it's throwing a sale on a number of games with controller support, which is particularly advantageous when you're crashed out on your couch using the big screen-friendly viewing option. Deep discounts of up to 75% are on offer. Be sure to check out Portal 2 in particular, if you haven't already, as it has a new split-screen co-op option.

Thanks, Rock Paper Shotgun.
