Lastly, aren't three of those twenty pictures images of the default BroShep?
It's really a pretty terrible image for purposes of this discussion. I think it makes a good point on the sameyness of male protagonists in (1) current-gen (2) non-Nintendo console games, but...well, that's a pretty ridiculous set of limitations to choose in the middle of a rant about how incomplete the Tropes vs. Women video is in only discussing tropes involving women. If we're to have a discussion about pervasive images in video games as a culture that influences its audience, any list that includes Dead Rising Guy but not Mario is sorta missing the point of popularity and cultural influence.
Shepard is an interesting example to look at because it would be pretty easy to dismiss FemShep as "man with tits" -- because, with the exception of a romance option or two, FemShep is literally EXACTLY THE SAME as MaleShep.
AND YET, instead we've got a character who's interesting and fully-developed even though the sex the player chooses is almost entirely irrelevant.
Granted, part of that is that both versions of Shepard fit into the "military hardass" trope, which yes indeedy is kind of a big one in games (and particularly in shooters, though that kinda stands to reason). The notion of a soldier who's a soldier and whose sex doesn't enter into that? Well, I'll grant that's a hell of a lot more aspirational than realistic, but given that we're looking at a Roddenberry-style aspirational future, it makes sense to depict a society that treats military women the same as men.
