In case you get this first, we declared this turn. The only force we brought was two guerilla II muskets and the purpose was to view/control a tile, maybe entice a battle at very favorable odds etc. (and we stole a worker in doing so). I think the element of surprise is gone; it's pretty clear to all what's going to happen. The only element left unknown (to some) is the issue of when. And here's a screenie for you guys to chew on.
Your numbers from above are a little off. This is more what we had in mind and we'd prefer not to stray too far from this schedule so if you could agree to this plan that would be great.
We're on pace (with some road building left to do and if TKY doesn't border pop) to move to the barren plains hill tile our muskets are on on turn 158, 960 AD. Due to the playing order, if you we're to enter onto a Zero-adjacent tile on turn 159, then on Sancta's turn 159 they would have to deal with our combined stacks at once.
We currently see Sancta on pace to get Chem in 4. It's very possible that they're going GS crazy (we did) and will pop one soon enough to get Chemistry like next turn. That gets them fairly close to Military Science and maybe they have the Taj close to completion and then they start whipping out grenadiers and such.
But given our timeframe, I don't think they'll have enough time to make much difference when it comes to TKY and Zero. Dragon Tears maybe, but even then we're talking about the combined force of our two nations; I think, as long as we communicate well and join together, it's going to be alot for Sancta to handle.
Where is their siege? So far their only double promotion troops are the knights coming every 2 turns from Sanctum. They don't have religion spread to utilize Theology effectively. I think they could catch up with some of the technology in those 9 turns (we'll have to watch and communicate that carefully) but won't be able to put it in the field, at least not initially.
Lets just take it one turn at a time but if you can raze Zero and, if the culture spread allows it, road (bring workers) yourself into the hills of Dragon Tears with some guerilla II redcoats I think we're in great shape. I still think they should go RP>Rifling and draft some and get Saturn on our tail, but we'll see - maybe that's closer than it seems.
So here's where were at, let us know if it's good.
And it would sure be nice if you could send over RP for our windmills asap.
