Which part of the world has the least civilizations?

ANTARCTICA AND THE OCEANS

Anywhere humans settled, there has been civilization. Of course, depending on the climate, the economy and other factors all regions weren't equal.

sub saharan africa is also extremely remote, and tropical. Both of which work against it.

Wrong, actually you had more than several in Sub Saharan Africa. Good example is Ghana, followed by Mali Empire, Songhai, The Hausa state, Karem Borno, Ancient Axum, The Swahili, Benin, Nok, Yoruba, Sao, Ashanti, Funj and to a certain extent Zimbabwe, and the christian kingdoms of Ethiopa, Makuria, Nobatia, Alodia.
