Walt on Uveto tells Steele Ausar culture thinks poorly of gene mods in general (sex changes are OK), so xenophobia might not be limited to humans. In fact, of all core races, humans mod themselves the most (I think I've seen that, trying to find a reference...).
Hey then in some places they could have a group that react to muzzle score and get angry with players about it.
Make it not just humans and have it be ausars in a different group all by themselves hating muzzles and being thought of as dogs.
Can we please not have -more- of Riya around? She's already bad enough as is and TiTS is -not- the game to tackle topics like this. It requires a certain level of thought, care and environment that just isn't a given for what boils down to a fapgame with sci-fi window dressing.
I can kinda see what you mean, tits is a game where you just mostly jerk off to, not like there are deeper things in the game to make it feel a bit more alive. But tits has its share of dark stuff in it, such as bimboing people, pirate slavery, murder, genocide and war crimes and a couple others i probably missed.
Plus racism isn't anything new to tits. Look at the myr for instance both golds and reds hate each other.
