So, this thread is for people to gather ideas, and share them.
Edit: Examples: Metalurgy for underwater civs, what your playstyle will be, how do you think new features will work. Ect.
I think future ideas, gameplay ideas etc. are better served by existing threads (and if one doesn’t exist a new could be started). There’s the miscellaneous talk thread that is almost the same as this, other than non-Thrive topics also go there.
