So I've been replaying China on the current version but I cannot seem to get compass in any good time. By 500AD or so I've got all my base cities set up and the income is positive and tech rate is decent, but I'm still behind in actual tech numbers. And yet consistently in about 3/4 games in a row now Byzantium invents Compass in 600-700AD, while I'm still about 8 techs or so away. Is there something that I'm doing wrong? I'd say, that with the following cities: Chang'an (1S from start), Luoyang (empty plains), Guangzhou, Kunming (next to gold), Beijing (next to fish), Shenyang, Hangzhou (next to fish), and the following building distribution: All have Taixue, most have market, most have Confucian Academies, one or two have Taoist Academies Civics are usually monarchy, slavery, clergy, citizenship, sovereignty at this period. Confucianism as state religion, in every city. My army is typically as follows: 2 Swordsmen on the Tibetan border. 3 Swordsmen on the Northern Border who were used to conquer Simiyan Hoton. 6 Horsemen with Skirmisher promotion to instantly wipe out any Horse Archer spawns. 1-2 Archers in every city. Terracotta Army, Great Wall and Dujiangyan all got by this point. Great Canal is nowhere near, however. I kept a scout in Constantinople the whole time to try get a tech trade bonus but no dice. My thoughts are possibly that: 1. I need to micromanage scientists. I typically have no or only one GP by this point, so perhaps I need more specialists. 2. I could use the early game civics a bit more. Typically I avoid Despotism and Redistribution, but perhaps I could spend some turns with them. 3. My army is too big. Maybe I could disband some units after conquering Simiyan Hoton, and take more risks fighting the Xiongu. 4. Expansion rate. I thought that I'd got my expansion rate at a good, harmonious pace but maybe I've still been going to fast.
