In terms of sheer value, it doesn't get much better than Amazon's 2K Mega Pack this week. Featuring 9 games in total, highlights include Civilization V, Borderlands, BioShock, and Mafia II. They're not the most current games you could spend your money on, but with a total discount in the ballpark of $225, it's hard to pass up.
