Publisher: Take-Two Interactive Software
Shares of Take-Two jumped nearly 20 percent in the week after the first "Bioshock" was released in 2007. It was more than a critical darling; it was a game with legs at retail. By March 2010, it had sold 4 million copies. A sequel by a different development studio did so-so, but with original designer Irrational Games back at the helm, fans are already lining up to get their hands on the game when it comes out in late February.
