That’s cool, but... what are we trying to imply with this data?
As you can see from some jokes in here (which did make me laugh and would get people banned elsewhere, alas), publishing this data could have the effect of reinforcing stereotypes instead of bringing them down.
(chill guys, stereotypes can be fun if you’re not the type that gets riled up at the mere idea, this is not a SJW post

)
Does it matter what gender you are if you’re having fun?
Does this data mean that... huh... “females” are going to surpass “males” one day as the gender that plays more video games? Would that be a positive?
Is there something inherently wrong with “females” playing less video games than “males”? Would equality of time spent gaming be a social conquest for women?
MK is cute, easy to pick up, and has enough characters to be “representative” of virtually anyone who wants to give it a try. Does this tell more about the game, or more about general preferences of women in gaming?
Because you see, if I sit down for a game of MK with one or more women, if they’ve never played the game or they don’t usually play games, I don’t expect them to kick my ass, but that’s not because they’re women, it’s because they’ve spent less time with the game than me.
I’ve had my ass kicked by women in racing games, fighters, sports games. This didn’t make me think “holy crap, a woman can be good at games too!” or “you know what, I’m gonna marry this gal!”. No, this tells me that there’s women who play a lot of video games out there (and why would that not be?), but this doesn’t change the fact that most women I know don’t play games or just like to chill with a little, simple cell phone game in their free time.
MK Tour isn’t a gateway for its female players to buy a console or gaming PC and start playing all kinds of video games.
So you see, telling me that MK Tour is 40% “female” tells me nothing.
I don’t see women playing games as women “intruding in my boys-only club”, and I don’t think more women playing games is a blow to the patriarchy and a great social conquest for women.
Women play games? The more the merrier!
