In Civ 5, the joint fastest HoF Deity Science Win (t193, vadalaz, huns) involved taking cities from the AI (planted four, took seven for eleven total).
In Civ 6, it seems war is more efficient than Civ 5:
No Science/ Culture per city penalty
Increasing costs building settlers/ districts
local, not global happiness
no automatic city bombardment
can use other's roads.
Given what we know, will capturing many (even all but one) cities be the most efficient way of winning (on Deity) for all VCs?
