Copies of Halo 3 for Microsoft Corp.'s Xbox 360 gaming syste

UNITED STATES - SEPTEMBER 24: Copies of Halo 3 for Microsoft Corp.'s Xbox 360 gaming system sit on display at a GameStop store in Marina Del Rey, California, U.S., Tuesday, Sept. 25, 2007. Microsoft Corp. took the lead in video-game players after it introduced the Xbox 360 in November 2005, five years after entering the business. With Nintendo Co.'s Wii threatening to topple the Xbox by year-end, Microsoft is looking to Halo 3, the latest version of the best-selling Xbox series, to rekindle interest in its console.
