Everyone knew that 3 kingdoms was a terrible DLC. Even the devs knew but they were too chickenshit to say so. They just pushed out two obviously unfinished DLCs frankensteined together in order to coincide with the PS5 port.
So now a 25 year legacy is dead and buried. I hope to fuck this game somehow gets good mod support in future so all this can be fixed and we can add as many new civs etc as we want, but I doubt it considering (((microsoft))).
