A survey by the Pew Internet & American Life Project (pew-pew!) has shown that 50% of American adults play games. Lazy bastards, why aren't they out shopping and working their way out of the recession, eh? Anyway, Gamasutra offers a breakdown of some of the results including this: "Older gamers are also more likely to play games on PC as opposed to consoles. Among adult gamers, proportional PC usage steadily increases from the 18-29 age group, to 30-49, to 50-64, reaching a high of 83 percent, then slightly dropping off for 65-plus. Meanwhile, console usage drops in parallel to a low of 23 percent."
I built my parents a PC, but they bought a Wii instead. Bah!
