All in all, this isn't too bad of a start.
I usually don't mind being isolated, because I like being able to focus on building instead of warmongering.
Your island's fairly spacious and has a good mix of resources (6

, 5

, Stone & Marble, Iron & Copper).
The one thing I hate about this island is the amount of Plains all over it. The food resources could use a shift, too. They're in awkward places to get in the fat cross with production tiles.
Anyhow:
I was lucky enough to pop 2 Scouts off the goody huts, so I used these guys to help fogbust. There was relatively no barbarian activity.
Starting with Mysticism and Marble in the fat cross = ezMode Oracle and GL. The 7 forests make it even easier.
With all the trees everywhere, I was able to chop- and whip-rush Courthouses and Terraces in nearly every city shortly after founding it to keep economic detriment at a minimum.
The Terrace is one of the strongest UB's in Warlords ... definitely get those up quickly.
Teching so far:
Polytheism - for Hinduism
Bronze Working - to start prechopping for Oracle & find Copper for Colossus
Masonry - for Marble
The Wheel - to hook up Marble
Priesthood - for The Oracle
Writing - Library + CoL prereq
CoL - free via The Oracle
Pottery - Cottage spam + UB
Alphabet
Literature - GL ftw
Animal Husbandry - to facilitate expansion cities
Metal Casting - Colossus ftw
Fishing
Sailing - for Lighthouses & coastal

Mathematics - for better chopping as I expand
Civil Service - for Bureaucracy
Meditation
Philosophy
Music - I just wanted the free Artist
Iron Working - I needed happy Gems
Calendar - I needed happy Silk
Paper
Education
Liberalism - for Free Speech
Nationalism - free via Liberalism (forgot to stop Liberalism @ -1 turn)
Machinery - traded Music & Drama to Alexander
Printing Press
Constitution
Democracy - for Emancipation and to bring up my cottages
Guilds
Banking - Mercantalism + Representation + SoL (soon) ftw
Economics - go go Wall Street
And that's where I'm at now.
Mansa Musa's GNP is greater than mine, but I'm hoping to match him soon.
I'm currently selling Silk to everybody but Genghis Khan (so as not to screw up relations with Roosevelt, who's at war with him) for about 6 GPT each.
The only resource I'm trading for right now is Corn.
The year is 1360, and I just finished The Taj Mahal.
I'm poised for just about any victory I want. However, the lack of production so far on my island has me leaning towards a cultural victory.

What did you do different, and where did it fall apart for you?
