Oh, yeah, what I do want from Assassin’s Creed 5, regardless of setting:
A main character with customisable race/gender, or, at the very least, a playable female Assassin character. Aside from being a good idea generally, they need to make up for the genderfail-snatched-from-the-jaws-of-victory in Brotherhood… *
*- i.e. the thing whereby it was possible to create a mixed or even completely female Assassin Guild, but in which the cutscenes for a mission involving them all showed them all as male.
