From what I gather, this expansion focusses heavily on expanding the colonial mechanics. In relation to this, have there been improvements to pre-colonial africa (it looks a bit empty)? It'd be nice if you could sign "treaties" with native nations much like European powers did in that era.
What do you mean, we already have this through colonizing.
With Treaties:
*makes treaty*
*goes through loopholes and breaks promises to conquer and exploit land*
Without Treaties:
*conquer and exploit land*
No difference really.
