In the continents maps, he does settle quite horribly and be a very weak opponent in general.The few times I've played against Kupe, he's chosen some pretty terrible places to settle. Things like a two or three hex peninsula sticking out of the equivalent of Antarctica. I thought it was just the random seed for the map, but if others have been reporting the same thing, then maybe he really is a bit lacking in intellectual vigour.
He does a lot better when you play an Inland Sea map.
Kupe does what Kupe wants
Was going to ask why you didn't go ahead and take the free settler...
Until I realized you're Canada... oh well
On the bright side there's no threat of early war...
