I always play as a woman, even though I'm a guy. So yeah, just play whatever you want to play as and don't worry about real life. xD
I did that on Mass Effect for two reasons
1. When I play in 3rd person, I have to wonder whether I want to spend many many hours with a man-bum pointed at my face.
2. When I heard about extra terrestrial lovin, the choice was only made easier.
God that sounds sad. :blush:
