Re: non story
"Female meshes abound. Add an extra mesh option with the same animation rigs, and job done."
A fine job indeed, too, if you assume the long, tedious, extra work of remaking the textures for that mesh, and also for every single apparel option, accessory, weapon, etc. that comes in the game and will combine with it - unless you're fine with insulting every female gamer in the world with a very non-matching texture of a guy's face and musculature superimposed (and way off) over a gal's body...
A fine job, yes, surely, with a wrong-scaled mesh that will look silly using animations made for a mesh where the joints are off, the bones are different length, the centers of mass (and thus, inertia of body in movement) are off, the attachment nodes for weapons and accessories are off and the wrong scale, etc.
A "female" character with very male grunt sounds when jumping, falling, hurting, etc. With lots of silly clipping, 90s style, with feet hovering off ground or ankle-deep in it depending on the action, "roller-skating" on invisible free-wheels as it walks and runs, with hands that lift or grab things at a distance by magic and wobbly fuse into walls and scales when climbing, etc. A testament to the long-standing quality of character animation in the Assassin's Creed series, indeed.
Mr Bailey I'm afraid you know very little of the video-game industry. I'm afraid you also know very little about female gamers, because offering a satisfactory variety of options for dressing a female character takes a LOT more work than just than fiddling with a male mesh and adjusting some proportions. And few things scream "shoddy" louder to girls than seeing leg / skirt polygon clipping on female characters in 3D videogames.
