I haven't seen gender effect actual gameplay. I play with both genders frequently. Only difference is that they rarely, if ever, play male characters. That's it.
I do believe that our brains are different, I just don't believe that it has any effect on playstyle.
Straight up. My distribution is a little weird just because I have like every Hayabusa player on PSN added to my friends list, but them excluded, almost everyone on my friends list main females. Same thing applies to the players at the offline events I've attended.
