2K Games has a pretty good deal going on right now. Everything in their online store is 50% off, which takes games like WWE '13, NBA 2K13, and XCOM: Enemy Unknown down to $20. Spec-Ops: The Line, Top Spin 4, and The Darkness II LE are a mere $10, while Civ V's Gold Edition can be yours for only $25. If you're into sports games, you'll obviously be in heaven here, but the non-sports stuff on sale is pretty appealing as well. Bioshock 1 and 2 are $10 each and in an amusing bit, there's even a PS2 and Xbox game on sale in the form of Mafia - which is only $5.
