When I was a young child, I would be pretty annoyed at having to play boys in my video games. Spyro, Crash & Pokemon. I still remember how happy I was when my oldest brother bought me Crystal for Christmas (I didn't have Gold or Silver,) and how my eyes lit up when the game asked: "Are you a boy, or are you a girl?"
Then I restarted my game as a boy because I thought that the avatar of Kris holding the Pokeball when you engage in battle looked really, really creepy. Hahah. I believe I eventually got over it and played as a girl on my second run.
But in all other Pokemon games, I've been the girl on my first playthrough, because I like to project that it is me.
I feel sorry for anyone who played a boy on X/Y and was excited for customization though. they got only 4 hairstyles.
