Seeing as I'm actually a tabby cat in real life, I'd love to see my feline brethren as playable characters in-game. THE CATS SHALL RISE. You've got yourself an upvote!
Also, As soon as the words "Roman culture" appeared. I had to make this; Sorry if the art is a bit rubbish, it was 2 in the morning when I started work on this. EDIT: found vote link, never mind.
I thought I could try to make some sprites as examples. Also tried to mix a Roman "Toga" with one of the original designs. Also: Vote link - http://playstarbound.com/suggestions/?p=view&id=5432 Your welcome
I believe one of the devs said back before beta, that races with tails would be awkward to animate. So, many races either omitted the tail or were yelled at by people who hate furries. Although, there are several mods that add races with tails. Not sure if they have any problems with their tails.
They do, and I think that needs addressing at some point. An anthro without a tail is just weird, plus if it has a long tail it's being denied the most appealing part of its body.
I really don't see what the issue with sticking a tail out the back of a sprite is. You don't need to give it armor, or anything it just inexplicably sticks out the back. I guess they would need to make a falling down, running, and swimming animation for it, but would that be so hard?
I'm really late but, it's the climbing animations and anything that shows the tail from the back. Because the armor is an overlay, the tail would have to also be an overlay in that situation. It could be modded in, but the devs probably didn't think it was worth it.
