It is very interesting to look back at the media's perception of Nintendo right up until Brain Age was released. It was kiddy this, childish that, no matter what games came out when. Didn't matter how much blood was spilled, how many swear words, how much sex. Kiddy kiddy kiddy.
Then Brain Age came out, an E rated game, and got very popular with men, older men, women, and older women. Record-breakingly popular. So now the "kiddy brigade" had a problem. How can you even say DS is "kiddy" when there are repeating images of 35-year-old men and women playing it. It just doesn't stick. It got worse when Wii Sports came out and seniors, older men, and basically everybody was playing this game. Even on day 1, Wii is popular with adults. What to do?
So they decided to rest on "casual" and now define "gamer" as this ever shrinking demographic window of a male 15-27. This is a fine time to bring up an old Cartoon Network show called Codename: Kids Next Door (I believe I have reviewed one of the licensed games on the site.) In it, a group of children fight against "adult tyranny" and their useful lackeys the "teenagers," the bourgeoisie managers of this whole growing up biz. That's not important but what is important is how one of these agents of the Kids Next Door gets decommissioned. The second they turn 13 they get their brains scrambled and they basically "go back to being normal." This is usually a tearful event as they lose good agents, but it's all for the cause and all that.
This is similar to the attitude most of these games press sites take, that older than a certain age makes you somehow a non-gamer no matter what your favorites are, simply because of the newfound popularity in games for 28-40 age groups and 41-65 age groups. You get drummed out of the corps, so to speak.
We never talked about demographics before this generation. The only one we even recognized was "kiddy," which was humorously stuck onto some of the best games of all time like Mario 64 and Zelda: OOT, and done so by charlatans on this "internet" that was all the rage. Everybody who played games was a gamer, period. Now it's all different and much the worse for it. We have these amorphous labels "casual" and "hardcore." They now let marketing intercede with development and have games "aimed at demographics" which usually fail. And we are now all at each other's throats over how "hardcore" somebody can be and this is achieved somehow by buying the most expensive things, which would probably make game companies happy if they weren't all drowning in red ink. All because of a pointless label put on the market leading consoles (DS and Wii) by forum fanboys and bitterly disappointed games press editors.
