The Losers
Console games make up the lion's share of sales, according to the ESA, but they're also mostly played by males, and are developed mostly for that audience.
Microsoft's chief Xbox officer, Robert Bach, expects that the new Xbox 360, which he hints combines Xbox and PC capabilities, will see males making up 90 percent of early adopters, typically categorized as the hard-core gamers, with females making up the remaining few.
Such predictions are assumed in an industry where females prefer online and on PC platforms (both of which they typically already access or own) over purchasing consoles like Xbox, Playstation, and Nintendo.
