You built half the cities I would have founded in the space around Kyoto. City placement should be much closer, do some research in the Strategy Articles forum under
RCP. You have a second core around a Forbidden Palace, but the cities around it are too far apart as well. Have a look at the discussions on city placement in
mcsniper's thread. I've attached a dot map showing a possible citiy plan for an inner ring. The two most powerful tiles in your early game were the two cattle tiles north east of Kyoto. One of them has no city using it, the other is two tiles away from the city you founded near it, so it wan't active until you had a temple and border expansion.
You only have seven workers and eight or nine slaves. If that's all you have had through the game then your early land improvements would have been very slow.
You have as many riflemen as you have cavalry, and you are building more, so I assume you are planning for failure, with excessive defence, rather than expecting to expand by conquest of your neighbours.
Choose your research projcts with care. Why are you researching Espionage? It may be a good idea, but you need to have a good reason for it as it's an optional tech and you aren't going to get any trading value from it.
You've never even traded for contact with the French. The more civs you know the cheaper your techs will be to buy or to research and the more diplo options you have. It would never occur to me to reach the Industrial with an unknown civ on the map. Look at
Moonsinger's trading training thread for some clues about trading.
You've built colosseums in lots of towns that could have been building military units. You have only two luxuries, and are using cathedrals and colosseums as expensive happiness buildings instead of exploiting your markets with more luxuries. You don't even have enough population in most of your towns to need this level of happiness support.
I'm a warmonger by instinct, but I think the early game priorities for any player, be they builder/warmonger/scientist, are the same:
- Create a settler factory to churn out settlers every 4/5/6 turns after 3000 BC.
- Build an effective core of 10-12 cities around the palace with two rings of cities at distances three or four, and six or seven.
- Build workers at a rate of 1.5 to 2 per city once the core starts to develop.
- Only build the improvements you need for your objective, and for the role you've chosn for each city.
- Don't build defenders.
- Build the Forbidden Palace as soon as possible near to the capital.
- Conquer a neighbour, hopefully winning a Great Leader during the war to build a new palace in the neighbours capital and create a second core using their cities.
- Conquer your home continent as soon as possible. Once you have only coastal borders you can treat your neighbours with contempt if necessary, as they are incapable of mounting successful seaborne invasions.
- Careful selection of research projects, and trading to your advantage at every available opportunity.
