I vaguely remember this strategy being called "cheap" in Civ IV, especially on lower difficulties, but given how ridiculously easy it seems to capture cities and no warmongering in the ancient era, what's stopping us from clearing a continent all for ourselves? I think this could be a viable strategy for all victory types since playing wide is powerful in Civ VI. Maintenance costs are much cheaper than in Civ V and in general, the more tiles and districts, the stronger your empire. It may even allow for earlier finish dates in some scenarios. What do you think?
