If you ask me, the chain of reasoning would have gone something like this.
1. Desire demons? Yes or no?
2. Sure, let's do desire demons!
3. Except, now that we're clear on the fact that our audience includes players of every gender & every shade of sexual orientation, we should probably vary the desire demons to reflect that. Male desire demons, female desire demons, maybe some androgynous desire demons? Hey, androgynous desire demons! I'll start sketching right now!
4. Wait... wait... wait. Male desire demons?
5. Okay, which will generate more rage: dudes who LOVE boob-fondling female desire demons but will RUSH to the forums to protest if they have to see a single hip-cocking, ab-rippling, hair-combing male desire demon because EW THAT'S GROSS, or leaving desire demons out entirely?
6. Silence.
7. Soooo... pride demons? We'll make 'em real big.
