Primary purpose doesn't always translate to 51% of use. My laptop is not in any way a gaming rig but I still use it for games more than anything else, but I'd still classify myslef as a primarily console gamer.
The difference between "gamers" and "video game players" is what I'm getting at. My mother for example has several games on her iPad and iPhone, yet if I called her a gamer she'd laugh at me. Admittedly I do not have any studies or data to back this up, but I think we can agree that "gamers" are made up more of males than females.
I'm not discounting them as a "video game player" I'm saying that the particular games that cater to that market are not really comparable to AAA titles like Halo or TES, or even "lesser" (for want of a better term) titles like DA or CK2. I imagine the audience is skewed male for all of those titles.
I agree that AAA titles are skewed towards "gamers" and mobile/flash games are not. I get that. The people earlier in the thread were responding to a poll about "video game player" demographics by saying that mobile/flash gamer players "don't count". They were creating an artificial distinction that the poll did not specify. They are in the wrong when they do this. The same way that people who take that same poll and use it as data to say that there are more female DA: I players than male players are wrong.
Those polls are only good for this: Who plays video games? The answer, whether gamers like it or not, is that there are more women players than male players. Video games have become mainstream to the point that gamers are the minority now. They almost certainly are not the minority in spending, but they are the minority in the pure-numbers stance. Also, keep in mind that many gamers are women and many male video game players are not gamers. There are also probably a lot of people who I might classify as a gamer, who wouldn't classify themselves that way.
Ultimately, gamers are a sub-set of the audience for the medium. They are the most passionate, the most vocal, and the biggest spenders, but they are just a subset of the audience. And, one has to self-identify as a gamer. If a 60 year old woman plays 2 hours of video games every single day on her commute to work and she considers herself a gamer, can I tell her that she's not? Is there a set checklist that one must go through in order to classify yourself as a gamer?
Now, again, if someone wants to make an argument that AAA titles should cater (I almost used "pander", just to be a jerk) to the minority (i.e. gamers), then go for it. There is certainly a strong argument for this. But it's not the same as saying that women don't make up the majority of video game players.
