Lets Talk Occult Appearance/Genetics...

I disagree with what you said about Vampires and Spellcasters, but I agree with Mermaids and Aliens. I don't see why all the Aliens need to be the same. I personally believe that Aliens look just like we do, they're just from different planets. Why do my Alien Sims need to look weird and be off colored? Mermaids need more to them as well, like the ones they had in the faux-documentary, Mermaids the Body Found. We should be able to make them look like creepy fish people without needing CC. Why, you might ask? Because when you download Mermaid CC all the flipping Townies in your game end up with Gills and weird ears etc. They look even more ridiculous that before, which makes me delete it all from my game and then I have generic looking Mermaids again!
