BioWare's space opera epic, Mass Effect 2, is Amazon's "Deal of the Day." The Xbox 360 version is currently $40, which is $10 cheaper than you'd pick it up at your local Quarian pawn shop. A PC copy is 40 percent off, with a $30 price tag.

At that price, one could pick up Mass Effect 1 and 2 for the regular retail price of the sequel. For those who like their sci-fi soapy and their shooters refined, this is a deal worth going through the Omega 4 Relay for -- see, if you play the game, you'll know what that means.
