Limbo for 800 Microsoft Points ($10) -- a 33% discount from its original price. Nothing says "happy new year" like running away from a menacing giant spider, while having a slug eating away at your brains.
We'd like to think it's in celebration of its esteemed position on the Joystiq Top 10 of 2010 list, but apparently it's just part of Microsoft's "Countdown to 2011" promotion. That means in addition to Limbo, you can download the Kick-Ass movie for 29% off. Like peanut butter and pickles, this pairing makes so much sense.
