An additional problem is that ten-hour lockdown for units; basically, I have a six-hour window when I can play undisturbed, every other time involves a degree of fuss. So, a problem may occur if turn ends at 18:00. Come from work at 17:00, move (assuming I wasn't able to move the previous day which will occur sooner or later) and then I can't move unites that day anymore. Instead, I have to squeeze that move in the worst hour of the day, between waking up and running to work.
And so this will only be a problem occasionally, and realistically does not matter much. Much more often will be the case where you would want to do some "machination" by moving units just before turn end en then immediatly after, which is exactly what this tries to prevent, and it's a good thing. Though I do not know what was prevented with this against me, I know that it prevented me from doing quite unfair stuff some times, and thats as it should be. This is not your browser based time sucking mmo game which awards sitting endless hours in game (they have such annoying shit like- this building finishes in 20 minutes, then you can start another one! no thanks that is stupid). Besides I do not know if you know: theres a limit of 4 hours per turn you can be connected to game, so there is no whole day for thinking, at least not while observing situation of the game. (which I sometimes think might be too large, I'd almost think that 2 hours would suffice, but reallisticly this isin't something I'm sure about)
I think you should play first and then comment on such stuff. This might seem like a big deal but when you play it matters a little. Only times I though about that is when - oh man possible attacks might be incoming and turn switches at night thats no good. Or oh nice I can take this territory faster (build city) cause turn change is on a very good time for me. In the end it ends up being a minor luck factor and there is no problem with that (well realistically you can plan your attacks so that battles would start to occur as turn change is in the right time of day for you, but maybe it would also be the case for your enemy? or maybe someone else will strike first!
And believe me as you have not played game, any time is not better than shifting moving.
