A number of Xbox Live Arcade titles are set to go on sale today according to Major Nelson, and CVG has evidently gotten the jump on him, providing a list of titles ahead of time. The Deal of the Week has a few gems, specifically Retro City Rampage and the overlooked The Misadventures of P.B. Winterbottom for 50% off for Gold members.
You also really can't go wrong with anything in the Microsoft Studios sale, outside of the lackluster Deadlight. Particularly, you really need to check out Dust: An Elysian Tail. It's my number one recommendation, and a brilliant, challenging Metrodvania.
