So having guys with nearly no clothes and a lot of muscles etc. is good, but having girls with nearly no clothes and big breasts is bad?
A BIG LOL
It depends on the game. You can't expect a Gordon Freeman in Ninja Gaiden or Street Fighter and neither a similar woman in that kind of games.
Also the point is invalid because you have serious male and female characters in serious games like Half Life 2, Indigo Prophecy, adventures, etc. created 100% by men.
Also, I found Beyond Good and Evil as a game designed for 13 year old girls. I suspect it has sold a lot between girls... it's a very feminine game in all senses, and having a over-musculated italian guy speaking shit to you every 10 minutes doesn't help the BGE supporters cause either. And Jade being a common girl? A black-chinese girl with green lips ain't very common in my town.
She has a very important role, she is a strong girl... yeah, I give you that, but Lara Croft too. Would Lara Croft be better with smaller tits? Is that the problem?
