Reading enough guids about playing Justinian of Byzantines I've made one way to get Guilds about 300 BC. Difficulty - Prince, Speed - Marathon You may call me a cheater but I have one option on: Random seed on reload You regenerate map to start with stone & grain/rice/wheat within city's fatcross. Phase 1 Techs: Masonry-Agriculture-Animal Husbendry... Buildings: Worker-Warriorx3-Pyramids until happiness cap-Settlerx2 While teching to AH you explore map with Warrior promoting to Forester 2. When you've got AH quickly settle city with Horses. After getting those Horses you may breath lightly. Phase 2 Techs: Mining-Bronze Working-Pottery Constantinople: Workerx2-Pyramids-GW Thessalonica: Worker Adrianople: Worker After getting BW you start chopping forest for Pyramids. When you finished Pyramids - adopt Representation & Slavery, turn off "Avoid Growth" and start Great Wall in Constantinople. This Wonder is cheap, so 2 chopped forest is enough to finish it. Phase 3 Techs: Polytheism-Priesthood-Writing-Iron Working-Alphabeth Constantinople: Chariot rush-Oracle-Forge Adrianople&Thessalonica: Granary-Library-Forge When you finish Oracle - choose Metal Casing After finishing Forge - choose Engineer as specialist for more Great Engeneer points. Note: Don't forget about GPP! Within 1 turn before GP spawn - make save. If it is Prophet or Spy - reload for an Engineer Phase 4 After Alphabeth you can do whatever you want with your tech way with little exception: You must get Monarchy to open Feudalism. Yor first GE will help you with Machinery, your second GE - with Feudalism It's forbidden to start Construction before you've got Feudalism, because Engineering has higher priority for GE. About 500 BC you will be able to start Guilds. 1. Make sure that each city has Library & Forge 2. Make sure that each city has Longbowman or two. 3. Turn on "Build Research" in all cities & start Guilds Phase 5 When you have Guilds you'll need siege, aren't you? Quickly discover (or trade) Construction Make sure that you whipped enough Cataphracts & Catapults.... Destroy them all Good Luck P.S. Don't forget that building Hanging Gardens is both good for byzantines who really need Health, and for Great Engineer points.
