It's inevitable that the increase in female representation will feel to an extent "not organic". People will criticize female leads more since it's not the norm, and often the characters are partially laden with intent to "support the cause" of feminism. I see the Uncharted 4 and TLOU2 strong female moments very much as a statement the devs want to make about their support. It can come off as preachy, but that's unavoidable imo. It doesn't necessarily serve the games' quality, but it's what the devs want to do so it's their choice if they want to make any statements about current issues and talking points in society. Usually people don't want to see these themes in games since they're gaming for escapism, so adding it breeds a certain amount of disdain. You need to be very careful of how to present any such hot topics. I had no issues with Ellie's kiss, but the subtext was pretty obvious, and it's not one of the reasons why I want to play the game. Her relationship status isn't of interest to me in that world, it's just flavor text for the character, and I do hope the game doesn't make it a main focus as that would detract from things I find more interesting.
As it is, I think there's a good amount of variety to characters in gaming, and plenty of female leads. Perhaps the female leads are starting to show some symptoms of the same issues as male leads though, with having certain generic qualities that make a lead character. The protagonists often do follow a lot of very tired tropes, be they men or women. If you look at the current cavalcade of female leads in western AAA titles, you can certainly see what design choices the devs like to make when creating a "modern strong female lead", and it's a relatively limited set of attributes. I do think it's better than the 360 era gruff American bro archetype, but not that much. I also feel like a lot of European devs try too much to ape the Hollywood tropes with their games, and that makes the Western AAA industry a bit too samey despite how much cultural variety there actually is.
That said, I don't think the amount of strong female leads will do all that much to make more women play games or join the industry. The industry being more inclusive is one thing, but that doesn't mean the majority of women are suddenly going to care one bit more about gaming. Making women more interested in gaming and STEM professions is going to require a lot more effort, and I'm not sure if there's any point to it beyond breaking any potential barriers for those who do want to be a part of it. I don't think it'll ever be 50/50. I do want women to be more aware and accepting of gaming than they are on the whole, and that applies to much of society even now in 2018. Gaming is still seen way too much as a thing for boys, and that requires an attitude adjustment from parents, which tends to take generations to actually change.
