I've a hunch that the way Mass Effect assumes you're playing a guy is part of why Femshep is so endearing.They gave both Shepards the same distinctly male body language (it's most obvious when Femshep sits with her legs spread apart) so to me she came across as a socially awkward schlub who's only truly comfortable while shooting things, which I found more interesting than generic-action-guy Manshep. I didn't like the default Femshep redesign, not necessarily because there was something inherently wrong with it, but because she looked more polished than I was used to thinking of Femshep being. And not that it's an original point, but the superior voice acting sure doesn't hurt either.
