Meaning the conclusion "no girls allowed" is just randomly inserted somewhere in the middle of a wall of text.
Just because boys and men were identified as a large audience and targeted with marketing does not imply that girls are not allowed.
Nobody is forcing you to choose either aisle in the toy shop. Just the other day I bought a playmobil horse for my son that came in a pink box. Whatever...
What exactly do they mean by girls not allowed? Girls are not allowed to play first person shooters? How would such a rule even be enforced?
Or the right games are not being made for girls, then there would be more female gamers? I think whoever believes that should go out and make those games. Put their money where their mouth is.
Never mind that there are already lots of games that are being played by lots of girls/women. "No girls allowed" simply has no foundation in reality whatsoever.
