So the four largest and longest-lasting River Valley-Ancient Civilizations, Mesopotamia, Huang-He, Nile, and Indus, (with Mesoamerica and the Andes as other non-river centers of civilizations in the Americas), were centers of complex culture that grew and prospered. Where else could complex and lasting civilizations develop? For example, could a Congo River Valley civilization develop? How about a more advanced Mississippi River civilization? And can the Amazon River civilization last longer? What other regions could be centers of ancient civilization, and what changes would have to be made to make such advanced civilizations grow?
EDIT: One of the requirements is for the advanced civilization(s) not to collapse, unless in a foreign conquest situation like Mesoamerica and the Andes.
EDIT 2: Preferably, writing and bronze/iron/some other metal metallurgy in this hypothetical civilization.
EDIT 3: There are a few posts about the Mississippi River, but weren't they a bit less advanced compared to even other American civilizations, like Mesoamerica and the Andean region?
