Just saw the ESA "Essential Facts" about videogames. I won't bother to link to it. What they're implying is that more "old people" (50 and over) are playing videogames than "young people" (18 and under) but they're:
A) not saying a word about the methodology they used to arrive at these statistics
B) jiggering the charts to prove a point
So, 26% of game players are over 50, whereas only 25% are 18 or under?
Well, it's 26% of "game players" (whatever that means - if you've played Windows Solitaire once are you a "game player"?) are over 50. And there are a lot more 50-100 year olds in the US than there are 3-18 year olds (I picked 3 because that's the age where my daughter was able to start actually sort of playing video games), so...the fact remains that a 10-year old is much more likely to be a "game player"--even with your mystery definition--than a 60-year old.
This makes me actually angry. There is no doubt some real evidence that the video game demographic is getting older...because we're getting older. So why distort it?
Read Tufte. Show us some real statistics about what age groups play what games how much. Use the same methodology over successive years and show us real graphs describing the change. Don't show us a big pretty powerpoint presentation with fat bullet points and bull@#% callouts.
