Is there

A mod that simply allows the tectonics to be played in the early era campaign?

[Gorrrrrn]

I don't think anyone has done a geological total war

did you mean Teutonics?

They don't emerge until turn 70. It is technically possible to implement playability but you can't do anything until they emerge
and the first few turns are scripted.

Better play a later campaign?

lol yes I did mean the Teutonics I just dislike playing the late era campaign.
