Yeah, I agree with most of your points but my game is liberlly sprinkled with the word forerunners as the translation from Maori to English in its real form (Literal translation: Tangata [People] Whenua [Land]) is Forerunner!
They were a people who were here in NZ before the Maori and actually taught Maori the foundations of civilisation.
Their artifacts (Trig Stations, Rock wall constructions etc..) are still in evidence as are their ways.
So I guess no sales there...
