An anonymous reader writes "Think you're a big gamer? According to a new study from market research firm NPD Group, to be considered among the real hardcore you'll need to play an average of 48.5 hours a week — nearly seven hours a day. This group of gamers is, on average, '29 years old, and — perhaps surprisingly — one-third of them are female. They're more likely to play on consoles than on the PC, and on average they've purchased 24 titles in the past three months — a bill that could easily run over a thousand dollars. But dedicated though they may be, the Extreme Gamers are just a small minority: a mere 4% of the US's 174-million-strong gaming public. '"
