Do you stop or control growth of your cities? Do you decide "okay this one must not go beyond 6 citizens", or do you try to achieve maximum pop in all cities? One of the least fun parts of Civ 4, for me, was making sure that each city didn't become unhappy the next turn. So I had an alarm to tell me when a city was about to grow, and I had to manually go and look if it was about to go unhappy, then decide to avoid growth, and half the time I forgot to re-allow growth again... I hated this. In Civ 5, now I only have one big number, but that doesn't change the fact that in theory, I have to decide which cities to stop growing. Or maybe you guys just rely on the penalty applied at low levels of unhappiness? What I mean is that once you hit -1 or -2 unhappiness, the only penalty is to make growth 1/4th of the normal speed. That is a kind of auto-control on growth... But is it desirable to accept -1 to -2 unhappiness? It certainly makes further expansion more painful. If that's the case, then I still have to select some cities to mark as "avoid growth", and I'm not sure how to choose them. And of course, I will still forget to uncheck these boxes later because my short term memory is horrible.
