Unpopular Opinion: I actually think it's going to take away from the game.
I don't actually like Gears, probably mostly because it seems a bit like a testorerone fuelled, butch thing with just blood, gore and soldiers shouting booyah as they chainsaw up people.
So why do I care? Because adding a woman to game designed largely with this in mind means that she'll either be exploited in some way, or she's just going to be a distraction as the developers try to prove to a disinterested audience that "girls can be tough too".
EDIT: When I say "disinterested audience" I don't mean me. I mean the people who like playing as American Football player soldiers with chainsaws.
... please don't hate me. My girlfriend would definately make a better soldier than me. I don't think women are flawed... I just think that this game... won't do it right...
