20 tiles instead of 21: Look at the screeny with the moved worker, it may very well be possible that an AI is on another landmass and still take one of our squares, so we may not need to worry being overran
Long term:
research to UN asap.
-Build science wonder city in capital
-Trade loads with the AI
-Try to have encourage the scientific AI's to take down others.
-Capture extra towns to increase our own research.
Mid term:
When we research philo, we should be able to trade for many ancient techs, including iron working and math. Options will be open to build swords if we have iron (better than CoZ here because we will then have an attack force much earlier) or SoZ if we do not have iron.
Short term:
I think it comes down a choise between 2 paths now.
1) We invest in building the collosus. Assuming we are gonna mine 3 tiles before we road, we lose 3 roads for about 20 turns for 60 total commerce. Maybe more if without going for the collosus, we would build more than 3 rods before mining. Assuming we settle on the ivory and have happiness for 2, we are gonna keep an average of 2 citizens happy for about 15 truns, costing us at least 30 commerce, probably more like 40 since the lux slider can't always be adjusted perfectly. So we spend at least 100 commerce and about 20 turns delay on contacts.
100 commerce by itself is nothing, but it can delay our philo research by 5 or so turn and it may be more than 100 if we properly focus on commerce.
If we go for col, we cannot spend any time building a curragh or MP and we should indeed consider joining in the worker (further increasing the commerce cost a bit)
2)We go for full focus on research and city growth, possibly we first irrigate and then remine the cows. We start building curraghs and MP. Then we add some disbandable that can be used to turn maybe a 25spt production into 1 swordsmen/curragh per turn.
This also has the advantage that our curraghs may have explored the map and can be disbanded by the time we want to start using our unit support for swords.
The details:
-Moving the settler or not: I think it's pretty much a short term issue and i think either excel or the test map should easilly tell us what's best.
-min or max research. Calculation or the test map could tell us how many turns we need to research it. IMO <35 = max, >42 = min.
-Golden age should probably be delayed until we have a proper use for the shields. Also maybe until we have the science wonders available to enhance the benefit.
In normal games, an early golden age will enhance your growth so that you will benefit for ages to come. In this case that is not so true. Therefore, it is best to delay it until Industrial age if possible.
