What's an underrated part of Thrive that you're excited for?

When a mod doesn't even know what subforum to post in.

Walking animations and doing everything in my ability to break them

I'm unusually exited for the multicellular stage. Most people are only exited to play as some giant hebrivore or vicious predator, but I'm exited to play some jellyfish blob. In this stage the world is somewhat virgin and ripe for conquering and any organsim that manages to diversify and spread will eventually shape the face of whole ecosystems. Imagine that the earliest ancestor of all arthropods died out. The wolrd would look completely different, the wouldn't be any insects, crabs, crill, crill eaters, flowers, insect eating vertebrates or insect eater eating vertebrates.
Every small change in the early multicellular stage could potentially have a butterfly effect.
I also imagine the transition from 2D to 3D to be breathtaking. The 2D view is kind of simplyfied and it doesn' t yet feel as if you're in a vast, menacing ocean, but once it's 3D you zoom out and theres nothing but deep blue all around you you realize you're a 1mm blob in a huge, almost empty sea... I'm looking forward to multicellular stage.

I look forward to being able to create a new culture and it's religion/philosophy. Culture, religion and mythology have always been the part of histroy that interested me the most. I really look forward to being able to create a 'primitive' religion and see it 'evolve' and spread. Like, it could start out a simple shamansitic faith, but as it gets more folowers and said followers advance in technology, it could become say, a Pantheistic faith. Then, the culture starts building houses and cities. The pantheistic god goes from a god purely based on nature, to an all-encompassing world spirit. Houses, memories, people, technology, plants, animals etc.. are all a part of It. Great temples are build, and new ways of worship are invented. The culture comes in contact with a new religion, one that's polytheistic, and believes in a clear contrast between good and evil. They adopt some gods, and make them avatars of the Pantheistic God. They create a devil figure, an evil god who wants to destroy their god. And so, the religion keeps evolving and changing. I'm sorry I made this post so long, but I really think that this'll create some interesting stories.

The transition from single cellular to multi cellular creatures.

making the most ugly thing known to man

I'm mostly hyped for the behaviour editor. I once thought of a way one could (sorta) make a kind of hivemind, with phallic-shaped creatures firing pheromones (or just coloured liquids), and "lesser" creatures (made using the caste system) that will then attack whatever hit it (Or maybe move to that location or something). I'd like to make this a reality in Thrive once. (I also want to see how another creature might evolve into a certain clour and have my troops refuse to attack them as the colour corresponds to the "pacify" command or something)
