Just recently got this wonderful game, and am about to spike my third campaign to do the fourth better.
1st - No idea what I was doing, got wiped
2nd - Ran into logistics/resource trouble, got wiped
3rd - Did logistics right, messed up badly building new cities (too far, no production and starvation), but winning battles
So, I have been reading all the posts in the forum, and now have a much more refined logistics, resource, and military plan, but there are still (many!?) rough spots in my basic understanding of the game, particularly about expansion after early game.
1) At what point do you consider building new SHQs? In my 3rd game so far, I am still only using one. (5 zones, ~1000 hexes) Is this a mistake?
2) Is there any consensus about upgrading zones vs keeping them un-upgraded as it pertains to QOL and keeping it reasonable in the empire to avoid issues with low happiness in developing new zones? I presume there must be a solution here as I have much map to conquer, but also lots of difficulty getting new zones to take off.
3) Is it ok to let private interests develop e.g. oil resources (I always take metal/rare metal etc.)? Do these resources need roads to them for private industry to take them?
4) A lot of people mention administrative strain in zones with far flung resources. What exactly is administrative strain and why the six-hex 'rule'? Do these distant resources consume something other than logistic points?
Thanks for your answers, and thanks for a wonderful game!
