This is a satire right?
Let me be brutally honest here, there have been strong women in JRPGs for as long as I've been playing them. The issue that seems to be at the root of this article is that not *all* female characters or heroines are presented as being "strong" or "adventurers". Sure there are plenty of "traditionally" (and by this I don't just mean in the Japanese sense) feminine characters in games, but then again there is nothing wrong with that because there are plenty of women with very similar traits. Like it or not women do *tend* not to be as aggressive or combative as men, and to gravitate towards certain kinds of professions. Nobody holds guns to the head of young girls and says "play with dolls", "enjoy Barbie Horse Adventuers", and similar things despite what feminists might imply. Sure there are plenty of exceptions, tomboys and the like who are interested in all the same thing guys are, but there is some truth to the simple fact that where boys are interested in action, combat, and adventure, you have girls enjoying their "Disney Princess" products.
Over the years I remember seeing studies talking about how without any real goading from adults, kids gravitate towards specific things instinctively based on gender. It does cross over so you see exceptions, but the definate tendencies are real.
As such, why wouldn't there be a proliferation of women in RPGs that follow these tendencies, tend to be fairly non-aggressive, and gravitate towards more nuturing roles? Why wouldn't you have a princess that acts like a sheltered princess?
I think the roles are pretty proportionate overall, and a lot of it had to also do with the world being developed at various times. Some games even include rosters like "Final Fantasy VII" that featured more than one take on the female RPG character. You did indeed have Aeris who played the "Damsel In Distress" role, but in comparison you also had Tifa who was the opposite, and then Yuffie who was somewhere in between.
I mean sure, you can point fingers at specific RPGs for having passive female characters, and if that was all there was I could see the point, but even going back to like the SNES days you still had games like "Chrono Trigger", "Secret Of Mana", and others which were mixing it up.
As far as Japanese culture goes, well that's a mixed bag to be entirely honest. On one hand it can be argued that a lot of the female super heroes they have produced were intended to be funny (the fact that it's a girl is intended to increase the ridiculousness). On the other hand even going back as far as like the late 1980s you had things like the original "Bubblegum Crisis" that were treating the subject of female heroes seriously. Not to mention the entire "Sailor Moon" thing which arguably turned into it's own genere, and was in part successful because it managed to do a good job of blending a lot of elements, including a fairly feminine portrayal of the girls involved with their super-heroism. In a counterpoint to people who would make "Cagney and Lacey" type jokes like "okay, now it's time for the Knight Sabers to put on their Hard Suits and pretend they're men".
I'm hardly a Weeaboo, but to me this seems like a feminist rant, jousting with an issue that isn't there, and hasn't been for decades.
Oh sure, Japan has a lot of problems with sexism in it's society, but when it comes to their fandom community (video games, comics, etc...) it's been pretty progressive for a while now, it just doesn't present things one way continually. You still have the damsels and distress, fairly "passive" female leads, and the like, but you've also got plenty of female action heroes.
Oh, and let's be honest... guys have taken a beating in Japanese culture as well. There are more than a few series where the guys are pretty much dishrags. I won't get into "harem anime" (though it presents more than a few examples), but look at things like say "Neon Genesis Evangelion", or even "Gantz" before the last few episodes, just to name a couple. In "Valyria Chronicles" Welkin starts out as pretty much a complete dweeb, and for a good portion of the game your pretty much going to be using a tomboy named "Alicia" as Audie Murphy if you want high rankings.
