but it would make pretty lame preorder DLC as well, & I think that there would be more than a few p***ed off people if you only had the option to play as a female if you preordered it.
Yes, but preorder DLC is nearly always lame. Usually it's just overpowered weapon or some special skins. This way, preorder DLC would actually mean something because the ability to play as a woman is quite important to a not insignificant number of people, giving people an incentive to actually, you know, preorder.
It's quite genius, really. In a deeply stupid kind of way.
