That's not edgy - that kind of beings wouldn't survive anywhere. Just like how Gold Myr and most female Treated females wouldn't be able to breathe or rest. But yeah, the game stopped caring for verisimilitude ages ago. Especially when it comes to satisfy a thirst for coolness and certain kinks.
First of all, age old response:
If you're upset about your kinks not being in the game, why don't you turn the energy you use for complaining into actually writing them into the game? I still never understand why you people just can't write the shit yourself and only complain about why no one supports your kinks and fetishes. If it's not blacklisted there's nothing stopping you from writing it except yourself.
Also if we gonna talking about things not being able to stand, fly or feed themselves, then lets bring up the age old question of Taurs and Nagas, sense they make more "sense":
Just like these bird taurs, regular taurs are literally just a human torso slapped on to horse (or equivalent animal)'s neck. The same with nagas, except it's the head of a rather large snake. Realistically,
you're arguing for, nothing about them makes any biological sense. Do they a human set of organs and a horse set organs? Obviously they can't lay on their side because the horse-half would be too heavy, etc. etc. Yet they're okay to you. These bird taurs would obviously have the same issues any taur would but people are willing to believe it in the context of what's possible in the setting.
Also we know basically fuck all about Phaedra II other than it being an irradiate mad max planet and it being an alternate starter world or whatever.
We have people with 50 inch dicks surviving relatively alright and get fucked by many things bigger than them without dying. We have fucking tree octopi on a jungle planet. We have people with breast bigger than their fucking body but have no real breathing or back problems. Nothing about TiTs economy makes sense. Every species runs off of sci-fi genetics and can breed with anything for the most part with limited assistence.
The people of TiTs can change their biological make up on the fly for a few credits.
Realism doesn't exist and most people only care about design insofar as it hits their kinks. For fuck's sack
