Okay, I'm going to try and point out a couple of things to refute the OP's argument rather than simply say how much she sounds like Cooper Lawrence. I'm sure a lot of what I'm about to say has already been said by others, but I'm going to try and be an adult here rather than resort to name calling, which is pretty much what I was doing earlier.
First off, regarding the complaint that Femshep isn't focused on at all in marketing/promo material: granted, but the majority of the gaming community is male, and it makes sense that given the choice, they would prefer to play as a male character. I know that's the case for me. Not that I have anything against playing as a female, mind you. But since I'm a male I tend to play male characters.
Secondly, regarding how Femshep moves like an "overmasculized woman", or however it was that you put it, I just don't see it. I think any "overmasculized" movements of Femshep can be chalked up to the fact that Shepard is a soldier. Gender has nothing to do with it.
Regarding the camera focusing on Miranda's ass: So just because the camera zooms in on her ass a couple of times, that magically negates all her character development/depth? It's a couple of close-in shots of her butt that probably don't even last 30 seconds put together in the middle of a 40-hour game.
I would also like to point out that while, yes it is possible to get the girls in bed without romancing them, doing so will not only end the chance at a true romance, but any and all possibility of further interaction.
Mass Effect is filled with strong, competent female characters. Ashley, Liara, Miranda, Tali, Smara, and Jack all demonstrate strength and empowerment in their own way. Hell, Morinth does as well, even if she is a complete sociopath and unrepentant serial sex killer. To try and say that it objectifies women and panders to "men who refuse to grow up" simply because of a percieved slight is ludicrous.
BTW, calling the majority of the gaming population "men who refuse to grow up" doesn't really help your case at all. It makes you sound like, well I don't know how else to say it, Cooper Lawrence.
