If you're an old-school PC gamer like me, you know that Sid Meier's games loads of fun to play (and insanely addicting). Concrete Software has some great Sid Meier's titles available in the CrackBerry App Store, and through November 30th they are all 20% off. Pirates (a finalist in the BlackBerry Developers Challenge), Railroad Tycoon and Civilization IV are all on sale for only $3.99. Each simulation has great in-depth play that is sure to keep you busy for hours on end. These titles break from the standard "arcade" games on BlackBerry, giving them hours of replay value. If you're looking to pick up a great game to kill some time after Thanksgiving dinner, check out the links below.
