Ideas for the Society Stage [Put your ideas in this thread]

It’s the same as the “Ideas for the Multicellular Stage”, but for the Society Stage. Please check out this link for more information about how it works in this thread : Ideas for the Multicellular Stage [Put your ideas in this thread]
Anyway, I was thinking about how the tetrads concept could be implemented into the game. Tetrads is a notion of culture, which basically describes a cultural element (what does it replace, what does it reject, etc.). I think implementing this concept as a feature might help creating a culture in the game.

Feel free to share your ideas!
