Well I won't be submitting as I had a false start (Decided the mountain was NOT worth the lack of early Wonder production) but so far its been a fun ride.
Decided to settle on the Marble instead of 1E. Why? 15% Marble + 15% Aristocracy = Great Lighthouse and Colossus

My goal was simple. Go one city, grab Lighthouse, Colossus, GE and NC. Then game RAs to get to both Navigation and Gunpowder together and quickly. That turned out to be turn 160. Anyways here is the writeup:
Turn 1
I settle on the Marble and send my Warrior after the ruins(since this is my second start

) I set up a Worker to build in the Capital and I research Pottery.
Turn 4
Got lucky with an early culture ruin. Next turn I take tradition
Turn 10
Pottery finishes and I immediately switch to a Granary in the Capital. My scouting Warrior gets to the second ruin and it gives me Calendar, SCORE! The next ruin gives me an upgrade.
As soon as the Granary finishes which I've synced up to when Sailing finishes I start on the GL. With the granary I can now work 2 sheep/hill tiles and another hill taking the time to build the GL from 33 turns to 14 thanks to Aristocracy. It finishes before Bronze Working so I finish that Worker and immediately after build the Colossus, GL and NC without break. During this time Askia DoWs but just mulls around on his side of the island.
By now I've picked up Landed Elite so I can work more hills and I've grabbed Optics, Masonry, Philosophy and working on Trapping. I bought a Trireme to start making contact. In the mean time I prime Civil Service and Theology for the RAs. I use the GL on Iron Working and switch to scouting for a place nearby with Iron to snipe for when I get Caravels.
I meet Hiya and Al, making RAs with them. For a while its uneventful until about 10 turns before the RAs mature when I'm frantically trying to not screw this up.
Turn 108
I've managed to secure the median at 533

and it stays here for the next 6 RAs (not counting PT and Rationalism modifiers) PT isn't available now so I only get 533/2= 266

from the RA but thats enough to finish off Theology and Civil Service. I decide to use the overflow to get Metal Casting
Turn 115
Al's RA matures and I'm 4 turns off from finishing Education. With a 3rd RA coming up from Darius I plink one turn into Edu to secure the overflow and prime more techs while waiting for it so as not to upset my median.
Turn 123
I finish Education and start priming Compass and Steel. I've also set up two sets of RAs between Hiya/Gandhi and Al/Darius to finish on turn Turn 148 and 157 respectively.
I finally research Archery at this point as Askia has gotten uppity and decided to march on me. I manage to hold on by a hairs breadth, get an archer and finish tradition with Oligarchy, wiping out his warriors asap.
I also find my Iron, a little 6 iron deposit on a desert peninsula to the south. Hiya settled near but not too close to cause offense when I snatched it up.
Turn 148
In preparation I have the following techs left: Horseback Riding, Mathematics, Steel and Astrology. I take out Horseback since its a dead end and place the median firmly back on Steel(533

) which I prime to 1 turn and then start working on Astrology. PT finishes 2 turns before they mature giving me Astrology, Mathematics and down into Physics.
I use the GS to pop navigation and start upgrading my fleet.
Turn 157
Queued up Physics, Steel and Gunpowder for the RAs. Physics and Steel finish and puts Gunpowder at 2 turns to finish. This serves me two ways. 1)I get my UU 2) It opens up two Renaissance techs to boost my Median for future RAs. I also grab Rationalism about 6 turns prior.
Now, what does the future hold? Well I'll be annihilating Askia for starters then Ill scout out my two possible targets for my free DoW: Arabia or India. Both are rich as hell. Probably Arabia though since Ghandi will have likely gone tall which would wreck me.
