[单项选择]House prices might be declining suddenly and car sales dwindling but one sector is bucking the global economic trend: the video games industry has never had it so good. According to figures released this month, British gamers bought a record 82.8m titles in 2008. That’s a 26% increase on the previous year, making the UK the second-biggest games market in the world behind America. Analysts from Gfk Chart-Track, the British research company that published the report, say that as consumer hunker down at home, 2009 is likely to be another good year. Britain isn’t alone in experiencing a gaming boom. In 2008 global revenue from games software added up to an estimated $32 billion (￡22.2 billion ) —enough to overtake DVD sales for the first time.
