With the early worker prepping mines, and Liberty to collective rules, the early slow growth can be offset a little with hammers. Of course, just to the east, lurks Hiawatha. He's usually one of the capable AIs, so I take his presence seriously. This map is some kind of Archipelago, so having a smallish, sea based capital is less of a problem than it could be.
I went three city NC, followed by a fourth on the large isle to the NW (which I was very late in scouting). Nineveh is on Iroquois lands, but has a 1-tile choke point so should be easily held. It's the best of my initial 3-cities, and if it had slightly better production would have been the NC location.
T100 East (3 city core, all settled before t60)
T100 West (a really solid city that could eventually become my best)
At t100 I've just finished Compass. That means a Galleass fleet and war. The attack ready for Hiawatha below. Next turn I'll have 5 Galleass, 1 CB, 1 Warrior, 2 Triremes, and a Siege Tower.
Siege Towers are amazing. Because of their +200% city attack bonus they can take the -50% Amphibious assault penalty without flinching. (I am fairly certain that naval units don't get the city attack bonus, but I might have not been immediately adjacent to the city when I checked.
Anyone know? ). Hiawatha mainly has Mohawks. These are not going to get the job done on a water map.
Frigates into Amsterdam (I still don't have any range promotions, but experience is building).
Isabella built a useful canal city so that I have faster access to Madrid, the last non-Assyrian capital in the game.
This leads to a t176 domination victory.
Fun map, but for this map type having a somewhat weak capital isn't much of a problem. Total isolation would have been a different story.
