Very thorough report. Thanks, Maquis!
However, I'm not convinced that war is the best way forward at present. Khan's cities may seem lightly defended but he is still some way ahead of us on the power graph:
As well as the individual cultural defenses, some of his cities are defended by walls. His borders have expanded sufficiently that our units will have to slog across several tiles to reach the nearest targets - giving him time to organise defenses, rush more units, etc.
What would be our motivations and objectives?
- Capture valuable resources? I guess the priority would be the iron, but for all we know we may have our own supply as yet unrevealed. Other resources, such as gold, might well be obtained by trading.
- Acquire more territory? I don't think we need it at the moment. With borders in their current positions there is space for us to found up to five more cities - and of course this doesn't take account of territory accessible by boat. Moreover, our economy won't allow much further expansion until courthouses / currency are available.
- Pre-emptive strike? There is no evidence that Khan is planning to attack us in the near future. The relative lack of defenses in his towns suggests the contrary, in my opinion. If we still have room to expand then so does he, and I'm guessing he also has space to the north and east for more cities. Provided we don't fall too far behind in power I suspect he will be willing to maintain the status quo for now. If we can share a religion and trade some goods we have the start of a beautiful friendship...
Assuming we are successful in battle, how do we proceed? If we raze Khan's cities then we risk losing the sites to Jules or Cyrus. If we capture them instead we risk crippling our economy (as Maquis pointed out) and therefore falling further behind in technology. And of course, while the war is in progress we are spending money and hammers on units rather than infrastructure and technology.
My view is that we should keep the peace for now and reassess the situation once we have catapults.
If war is imminent I think it is more likely to be between Jules and Cyrus as they are already rubbing borders. Curiously, though, Cyrus appears to consider Khan his worst enemy, rather than Jules. Either way, I think we should now consider closing borders with Cyrus and opening them with Jules.
Speaking of diplomacy, I also think we should move for Alphabet with some urgency, before we get locked out of the tech race - we know Jules had Writing some time before we did, and Khan already has Monarchy, so it seems we are already falling behind. Moreover, Alphabet will also allow us to plan our own research strategy to complement the AI - a better option than simply chasing the most popular techs.
What I'm proposing is that we bolster our defenses on the front line, but build some more workers (cottages) and libraries, grow our cities once we've revolted to HR, and try not to fall behind in tech.
If Cyrus (or even Jules) declares war on Khan then we could consider taking advantage of the situation while his back is turned; otherwise, I just don't think it is worth our while.
Thoughts?
