It wasn't until about the late 80s and early 90s--when video games were marketed as toys for boys--that the idea cropped up that games weren't meant for girls, and the developers responded to the dropped female audience. It became a self-fulfilling prophecy that has only been brought into question recently.
I grew up with pokemon and every kid in my first grade class either had a gameboy or watched kids play one, as pokemon was a genderless and fun game experience. I had sixth graders challenging me to battle, I had fourth graders trading with me to fill their pokedexes. It didn't matter your age or gender. Games were for everyone was the message I got.
But as I started to use the internet, I came across guys that were mad that girls were playing "their" games. I never came across this attitude in real life so I thought it was a joke. And maybe it was, at first. But I think the mid 2000s with it's pandering character designs, dudebro marketing and generic white man protagonists only solidified this idea. I remember about 2006 to 2008 I took a video game hiatus (maybe I was tired of being told I couldn't play them). The game that brought me back was The World End With You. I loved it to death. A game were it was just a fun romp like the RPGs I used to play, with a modern setting and better writing than most games of my youth? Sign me up!
Then I played Assassin's Creed, and realised that games were evolving on a technological scale. I played more games, ignoring the whiny boys. I sunk a ton of time to the Assassin's Creed multiplayer and became a top player. I was having fun again! The Last of Us had a great character in Ellie and Naughty Dog steamrolled a company that removed her from an advertisement, and fought to put her on the box art in clear view. Yes, I thought, the game industry is improving!
So I always want to just roll my eyes when guys say that "that's just how game design is". No, it's not! Ask for change in the industry, don't support games that you don't agree with their design choices. Go to panels or Q&As and ask them why something is like is, if they can't rationalize it logically in two seconds you know they didn't think about it. Make them think about it.
