I have never been able to play a female character. As sixist as it may sound: women don't fit in the role of hero. I don't know why this is. I know that in the real world and in modern times a female has the same ability to be an "Earth saver" as a man. I just can't do it though. A woman doesn't just stop the Oblivion crisis! A woman doesn't just kill a dragon when no one else can! A woman doesn't just FUS ROH DAH!
I know it might sound incredibly sixist. But women simply don't do these things in any story, fiction or non fiction. Joan of Arc is the only case I can think of to the contrary.
Playing as a female thief or assassin character doesn't make any sense to me either. The only place where a woman belongs for me is in the Mage's guild. I don't know why but its the only place where I feel they belong.
Call me sixist, its what I am calling myself right now anyways.
I know you know you're wrong for thinking this, but do you know why you think it, or is it just something in your head.
I'm a guy and I'm 100% against sixism, it actually kinda pisses me off, I don't know why. I have some examples of BA and amazing female characters in recent games:
Miranda Lawson from ME (I have a very unatural attraction to her)
Liara T'soni from ME
Leliana from Dragon Age
Lightning from Final Fantasy XIII
Tali Zorah vas Normandy from ME
Trishka Novak from Bulletstorm
Anya Stroud from Gears of War series
Sam Byrne from Gears of War series
Bernadette Mataki from Gears of War series
EPIC actually makes it a point for there female characters to be awesome.
EDIT: Oh, and a FemShep from ME and a female Warden from Deagon Age are amazing as well.
