I've been playing Civ most of my life, and recently I made a significant jump in skill level, winning a year ago on Prince, now winning on Prince 100% of the time, and now playing King and Emporer difficulties. Part of the jump is due to understanding that wasted actions (like building a Barracks when I don't need one) is using up valuable production and time. Recently I've started experimenting with ICS-ing, and I've encountered a situation that I realized I'm not sure what to do with. I'm playing with 11 other Civs, and I'm tied for the lead in points (me and Darius keep going back and forth). I have 19 cities (another about to go down in about 10 turns), two of them are sitting at 12 pop, three sitting at 2 pop, the rest 5-7 pop. I have a large standing military but only two other people on my continent, one north of me (strong, but not as strong as me), one south of me (last place on the leaderboard). My question is: What do I do when I have nothing to do? It's two parts really: 1. What should I be building in my cities when there is nothing in the build list that I really need? I have enough units, and any buildings I build will cost me money with little benefit. I currently have many of them giving me extra science, but that's a small contribution and seems like I should be doing something else. 2. What should I do to pull into the lead? Right now I'm just sitting around doing nothing. I don't really want to go to war with my neighbours (managing 20 cities is exhausting enough - I don't want more), and the two people who are in the lead with me are VERY VERY VERY far away. Attacking them is not practicable. Currently I'm in the tech lead, and just about to enter the Renaissance. Help?
