What gets me is that some people think it's less offensive to make a male and female character an interchangeable, soulless husk rather than a compelling singular character of either sex.
As a guy I'd rather have a compelling female character over an interchangeable character just as I'd prefer a compelling male character over an interchangeable character. One way the other doesn't bother me, so to say that it is a result of sexism is bizarre. It's a result of wanting a quality piece of content with strong, coherent narrative-character connection.
Perhaps it's a result of AC going all-out RPG making the idea of character selection more fitting, but for me, the arc of Altair/Ezio etc. was fundamental in the series' identity; as were the charm, atmosphere and motivations brought about by it.
It's like when you look at the new Ghostbusters movie, it's not that it was all women (although I struggle to understand how certain crowds are fine with hand-me-down characters), it's that it lost all of it's charm and identity, it wasn't really a Ghostbusters film. Ghostbusters was dry, sarcastic, witty and surprisingly understated despite the subject matter, it was not an in your face free for all. Yet anyone leveling a reasonable criticism was often grouped in with a tiny minority of arseholes who were genuinely sexist.
It's not about male/female one way or the other, it's about quality and what works for the content.
