We've seen some pretty comprehensive breakdowns of how the U.S. gaming industry performed last year -- however, industry analysis firm GfK-ChartTrack recently compiled a sizable amount of data to inform us how the whole planet did. In short, the planet did okay. U.S. sales faltered somewhat, the U.K.'s past-gen console sales sunk like a rock (or, rather, an original Xbox), and Japan stayed afloat upon a makeshift raft of Nintendo DS RPGs. The worldwide best-selling game of 2009 was (you'll never guess) Modern Warfare 2, with 11.86 million units sold. The runners-up were all proud members of the casual Wii suite: Wii Sports Resort, New Super Mario Bros. Wii, Wii Fit Plus, and plain ol' Wii Fit.
