Zogar, you have said a lot of things where there is less MM than in civ IV. Now let me add the ones that have more.
First, unit movement in general. The 1 upt and derivates lead to a qute big increase of fine tuning the units have to do just to not have clogs. this is not a trivial issue in any sense, since it affects pretty much every aspect of the game. And it is not restricted to the military, since non-military units ( workers, settlers and GP ) have 1 upt as well. This makes the game very MM intensive even with little number of units ( it even reminds me CivCol caravans
)
Second, research. Due to the fact that there is no research overflow, you should MM your science output to not lose thousands of beakers out just because. The issue is that this is hard work without a slider
and forces you to go to specialist management just to avoid losing beakers. This is quite a high level of MM needed , far more than in civ IV or even III ( that didn't had overflow, but had slider )
Third, happiness management. Given that happiness is global in civ V, you need to control carefully the ammount of pop you have and rate of growth of every city, especially when you are hovering near a
phase transition ( if you aren't you are probably not playing as good as you could ). This means more MM at the citizen allocation level.
Fourth, specialist allocation. IMHO the fact that you actually can choose between what GP you get by hiring/unhiring the specialists in question makes room for far more MM than in civ IV , where there was little you could do to for manipulating results in that way .
IMHO this four items alone increase the MM so much that the cutdows of MM you have in other areas are completely eclipsated. OFC that you can at the current state of the game to pretend that you don't need to fine tune this things, but as soon as the AI starts playing civ V instead of "throw units at random" , this kind of issue will be surely more noticed, especially in higher levels.
OFC that you can play without MMing the issues above, but that applies to all of the other MM of previous games
