slightly huh? this site is called civ
fanatics
actually theres also a
study about this
Well, we can't really know how much the poll being on this site affects the vote results. This is a problem with
any forum, though, as casual players typically don't go to them. The only reliable way to poll them would be to have the poll be within the game itself, which would be awkward and confusing, to say the least. I just went with my gut with the 50-50 or 60-40 number, but you're welcome to use any numbers that you want. Fwiw, I'll make another, better construced poll closer to release, as more new members will have joined the forum (and we'll know much more about the game) by then.
As for humans only remembering 7+-2 things, that is hardly relevant, as you don't have to
keep every city in your memory. You can see their size, produced item, etc, at a glance whenever you need to. If anything, Civ VI makes it easier to manage more cities, as the buildings can be seen directly on the map, so you'll instantly know that the city with the yellow roofs nearby is your commercial hub, etc. And realistically you'd only start to forget such things when you've got dozens of cities, which likely won't happen in a regular game of Civ VI, as they would've already made a remark or two to that effect (it being such a huge departure from Civ V).
