Hittites:
Small island start (space for 10 towns at strict CxxC), Iron + Horses but no freshwater, took me ages to conquer the Romans on the larger island next door (using Maces), the Dutch to the south (using Cavs), and the Iroquois halfway round the world (Cavs/Tanks); eventually lost a Space-Race to Egypt
Koreans:
Tiny island start (5 towns at Cx[x]C), no freshwater, Iron appeared under an already-founded town; 2 tiles from a 5-Civ continent (the other continent held the other 6 Civs); Maces eventually conquered the neighbouring Ottomans, but then the Egyptian/Viking Cav+Rifle-invasions started, gave up
Ottomans:
North end of a long stringy Continent, 2 Luxes and Iron-Mountains but no freshwater; preparing to invade the Germans to the south by building Warriors for upgrading, but just after I'd hooked up my Iron, the Vikings started massive cross-ocean Sword-invasions; lost my Wine-town and then my capital, gave up
Arabs (current):
Got tired of island starts, so chose a 70% Continents map this time; rolled a decent-sized island all to myself — but 90% is Tundra/Hills, with a 1-tile frozen lake, and no resources. Founded a small core at CxxC, beelined to Philo, made it first and took Lit, converted a build-in-progress to the GLib, but then lost the tech-monopoly
and the GLib to a SunTzu Wonder-cascade
(Still) can't reach the nearest continent safely (lost about half a dozen Archer-filled Galleys trying, eventually managed to land 5 Archers — just to take a
single crappy Iroquois Tundra-town as a foothold...). Now ICS-ing and Culture-building, while trying to reach Astro to re-invade with LBMs+Trebs — likely vs. Cavs + Rifles/Infs, at this stage...
