poeticadventurer, are you for real? You're asking for a possible reason why there now are more games that features female protagonists as well compared to before?
If anything we now get a variety when it comes to the main characters' gender and in my book variety is not a bad thing. If there is even the slightest chance that this also will make more people (in this case more woman) play games then I can't see that as something bad in any way.
