There are many places trying to do that already. The problem is many women in fact like stereotypical games catered to them. Aka, they are fine with stuff like dating simulators, digital dress up dolls, and facebook games. (Heck,even I like some of this stuff! Hey, don't judge me,bro! lol.)
Then you have the rest of female gamers who are just like us. Aka, girls that like Skyrim,girls that like Final Fantasy,girls that like Lollipop Chainsaw, girls that like Gears Of War, and girls that like Mass Effect. Some of these series have in fact "changed" to cater to more females already. (For example, Gears Of War 3 has playable female characters and one of ME 3's biggest selling points was promoting female Shepherd more than male Shepherd. Final Fantasy "always" drew in females because of its' dramatic spectacle and bishonen pretty boys.)
The problem is there are schisms even within the feminist movement itself. For example, you have feminists who do shirtless "slut walks" (Yes, that's the term "they" use) to promote empowered sexuality then you have feminist who think any kind of titillation,nudity, and sexiness what so ever is some kind of huge patriarchal conspiracy to keep women down. Aka, even if you managed to please some of them others would still be pissed off. It's a very no-win situation.
Lastly, feminists really don't speak for "all women". Think about it. What if I said I spoke for all gamers yet said many things you personally disapproved of? Would that be fair? Not really. "You" have the right to speak for "you". Nuff said!
When feminists start to organize more relief efforts for truly oppressed women in 3rd world countries I'll begin to give them a lot more credit. However, usually they just bitch about petty bullshit."Bouncy boobz in gamez,oh fucking noez!" Yes, the world must be ending. (sarcasm)
It's true some games are chalked full of puerile humor,exploitation, and objectification. However, there are many games that don't pander to that same crowd. Personally, I like having variety. Sometimes I like ditzy cheese fests like Lollipop chainsaw or Mortal Kombat but on other occasions I want a more deep and thoughtful experience akin to Nier or Bioshock Infinite. Can you imagine how boring games would be if they all had a set of strict guide lines to follow so as to not offend "anyone"? It would be terrible.
Lastly, the only reason I bring up "feminists" is that the woman "trolled" in your example happened to be apart of feminist frequency. That doesn't make her a bad person but it does mean she's associated with someone who really is not a "true gamer" despite playing games for research. Besides, I'm sure those same trolls go after certain males they dislike too. If you can admire one thing about trolls it is that they don't discriminate. lol. They're usually assholes to everyone.
