We have more than enough female representation in JRPGs, but they're all named after men and pretend they're men.

Lightning is a goddess so she counts for at least 400 women.

Any JRPG.
Tomb Raider
Princess Peach?
Any of the "imagine" games?
Heavenly Sword woman... i dont know how to spell her name
Jill Valentine, Ada Wong.
Mirrors Edge, Golden Axe.
Any game what lets you create your character... as a woman.
Left 4 Dead.

Theres loads if you REALLY think about it.

It does become quite the sausage fest after watching playing as a man over and over. 20 out of 737 is a larger difference than I thought. Hopefully FFXIII will give lead girls a second wind

when i play a game i don't mind if the protagonist is a man.. i'm playing for the experience :D the fact that the main characters are males doesn't really make me any less likely to play a game.. sometimes, it even seems that a lot of girl-protagonist games are AIMED at girls.. and tend to not be as good/difficult/whatever as other games.

anyway, i don't think it matters what gender the characters are :D
