Do you micromanage the tiles of your city screen? I am not talking about simply setting your city to production focus and locking down food tiles (which is what I usually do). I am talking about actively checking each one of your tiles in the city screen, almost every turn, to see that growth and production are both being achieved on the shortest number of turns. Here is what I mean: In this screenshot (Poland, on Diety), you can see that I'm building Porcelain Tower (PT) in Warsaw. The city is on focus, with all max tiles locked. I've got 19 in Warsaw, with 1 turn to get to 20. It will take 15 turns to build PT. Spoiler : Now here, I've moved some of the tiles to production to cut down on the PT. I've still got 1 turn to get to 20, but now PT will just take 11 turns. Not bad! Spoiler : So here, I've moved more tiles. PT will now only take 10 turns, but you can see I went too far. It will now take 2 turns to get to 20. I don't want that! Spoiler : Finally, I've got the perfect balance here. Just shuffling one more tile gets me PT in 10 turns, while still getting to 20 in 1 turn. Spoiler : After the next turn, I repick the tiles, then shuffle them around accordingly in the later turns to keep the turns on growth and production as low as possible. Is this amazing, or am I a total noob? I saw Moriarte1982 doing it in a recent video. It seems to work best when the city adds a , builds a new building or even if a worker develops a new tile. I am no Civ5 expert, but I am achieving faster benchmarks than I have previously. For example, I got Education at T105, which I usually do not get until T115 or later. I also got Leaning Tower and Globe Theatre in this game, which I almost never get on Diety (in addition to Pyramids and PT, which are easier to get).
