OK so here we go, lets start with a bit of MMing
Make Ulundi grow again, it has 3 spare

. Also start a granary in Nongona in favour of the lighthouse beeing build.
<Press Enter> *Chit I forget to look for trades*
So 1310 I check for trades and NO ONE has anything to give us, except poor Mansa who is beeing bullied by HC. Mansa is only willing to give us one tech at a reasonable price, IMHO, so I just take this one:

I also open borders so I can land the Explorer and start scouting around that land...
Offcourse getting Engineering shuts down our UU, which I only realize after the fact
1350 is a busy year at the palace as 2 new leaders come to visit our humble dwealings...

Alex, we all love to hate him. More so cause he has NOTHING to trade (from) us. Kublai on the other hand is lacking Paper and is proving himself to be a highway robber! No way I am taking that deal were we spend our entire live savings (sparing only 9gold).
While tracking thru Mansa land I notice he is at war with HC and (IIRC) Alex. HC has a nice gathering at Gao, one of Mansa's cities and he is bombing the defences... It should soon fall and sure enough a few turns later Mansa comes visiting asking us to join him against score leader HC.

Just the turn after, Alex (IIRC, it wasnt HC but the other guy not sure "the other guy" is Alex but I am 90% sure) asks us to join in. This time I say yes and we are at *phony* war with Mansa, scoring browny points with HC and Alex (again IIRC).
That very same year (1400, or actaully on the innerturn of 1390 so techincaly its 1390 I think) Gao falls to HC's forces.
I think to myself, Yay I made a right choice
Then 1400 we have another *nucliar* visitor in our palace, it is the Korean leader Wan Kon.
Because I turned up science to 100% in 1380 we now have Calander (In hind sight we lost the cheapo Monuments, was this a good choice?)
But we find that Wan Kon is needing something. He is down Paper, Engineering and Optics. So I trade him....
We have one more AI to meet, which accoording to the map of Wan Kon should be Gandhi! Who is north of Wan Kon, we should meet him in 3 or 4 turns so we have the set compleet!
If we run 100% science we have -93gpt and Astronomy will take 17 turns. But we only have 485 in gold reserve...
At 50% running -14gpt, Astro will take 32 turns!
I started University of Sankore in Ulundi.
1) We have nothing much more to build there
2) We have absolutely N O use for it what so ever! We
need the Money.
Maybe it would be smart to research Guilds before going for Astro, this would enable use to build Grocers and make our economy 25% more stronger.
On the other hand, Astro would open up traderoutes for us to others. Therefor help our economy immensly...
The world as we know it!

Notice the Judaist block of Alex and HC, for which we now are browning "mutual struggle" points!
Also notice the 2 "lost" cities of what looks like Mansa and Louis to the east (marked with white arrows)
WOW I just noticed this, Look at HC's capitol ! ! ! ! ! ! Size 23 allready ! *Geez*

The second (Budhist) island of Wan Kon and Gandhi. Notice the Confused religion also in Delhi!
Gandhi owns both Taoism and Buddism, Buddism should be netting him some nice gold presuming he has the shrine!
Lastly The save is here
