I want more divercity. We got mostly big-breasted western girls. Orcs, demons and gyarus was a good addition.
So why not more small-tits? Color ones? Furries (Don't like them, but why not. And thery was Holy Gadged, after all.)? Gnones? Monstergirls?
Even oozes can be tamed by the Magic Wand of the Hero.

So the only restrictions here is an international laws and males.
