Unlike other toys, video games belong to a certain generation rather than age group:
A new study by market analysts NPD shows that the average video game player is 32, up from 31 last year. That is a dramatic change from the Nintendo days when the audience was mostly pre-pubescent kids. Curious, I searched the NYT for “average age” and “video game,” and it turns out that the average video game player is whatever age someone born around 1978 would be at the time of the survey, from 1990 to 2010. This is only for home console game systems like Nintendo, Sega Genesis, PlayStation 2, etc. Computer game players tend to be 5 to 10 years older, but still their average age is however old someone born in the late ’60s or early ’70s would be.
Contrast this with the age profile of people who play with action figures — their average age stays virtually the same across the decades, somewhere between 5 and 13 I’d guess.
