Got the save, will play it.
I've noticed that we do not have Pottery: I know from the turns I played yesterday (that ended up not counting) that the Sioux have it. On the other hand, they are Neutral: they will likely ask for a (probably tech) gift. But they are our Key Civ so not that big of an issue. (but it could affect our research for Trade... I'm going to hold off before we discover that.)
3 triremes? I don't think it's a good idea. But again, neither is a settler from Madrid... will take the first option. I will need also to colonize land mass 13: Will use Cordoba settler as the Seville one should improve Toledo I will use the Cordoba settler (make it board the Cordoba trireme) and go thru the canal site that a city will soon be built on. One trireme should go exploring east (with units inside, obviously... but not Settlers, probably a warrior from Madrid) It will also reveal some hidden ocean tiles near Seville, and maybe a sea special if we are lucky! The last one... no idea. It will probably stay for domestic transportation, or go exploring west.
I think that building a wonder RIGHT NOW should be our top priority. 2 civs are building the Colossus: One will likely switch to Pyramids. This leaves little room for error if we want to snatch both Marco's and HG. We can use Caravans, granted (when we get them) but we do not have enough cities to do that at my liking. It is fortunate that we can use 2 good specials at Toledo to catch up! If we mine the Oil square, Toledo will produce 7 shields (not counting support costs) and 2 food surplus per turn at size 2. The question is: By building Marco's first, do we risk losing out on HG? (with poor trading terrain, we will NEED HG for WLTPD if we do not want to maintain insane luxuries for few results, especially that quite a few of our cities won't grow that much without extensive irrigation work, hampering our results)
Building a city at (121, 89) or (121, 87) should override the building of a city at (120, 82) atm because it will restrain the Sioux expansion north if they break the alliance (they do not have ZOC restrictions because of the alliance, so they can simply slip by our city... and I think losing the alliance could happen sooner than we could think... the Sioux need to be dead by 1480 AD max atm if we are playing with restarts, as I do not like having a ground neighbour) Getting wonders built (or near-built), expanding to 12+ cities and restraining the Sioux shall be my top priority in those 15 turns. Also, the Sioux do not have BW: If we want to attack them soon, having to deal with only warriors (and the odd mounted unit) will help. But a campaign is way too early right now IMO, and they will likely have BW by the time we are ready. We should wait until Crusaders, if we want to take that path. (and all that, is being said assuming restarts are on)
