Late as usual, and I didn't take notes for this one, so I can only contribute a few general observations.
I went Pottery first and then went for Writing -> Philosophy, but was beaten by 2-3 turns! Also the turn before I finished Republic, it was discovered by another civ and traded to a second, so no monopoly on that one. (Also I overran research by more than 100 beakers, because the price on Republic had dropped so much! Should have researched slower...

BTW the same happened on one other tech (can't remember which; Monotheism?!), where I was beaten by the AI and wasted around 200 beakers because of the price drop. BTW: did anyone ever notice: even if CivAssist says the current price of a tech is let's say 800 beakers, and you have already collected 1000 beakers, you don't get that tech the next turn, if you set science to 0%

You need at least 10% or a lone scientist.)
Nevertheless I was able to do some good tech trading. I think I became Republic around the same time as Megalou became a Monarchy, and entered the IA around the same time as him. (Don't know the exact numbers any longer.)
The barbarians never were a problem for me. (Lost a worker once due to carelessness.) In the uprising I was lucky: there were about 3 barb nests on my continent at that time, but one my horsemen took care of (got like 5 elites out of that), the other one was close to a Scandinavian town that they had settled on my continent, and I was able to watch a horde of barbarians destroy 2 Scandinavian spears and then "vanish" inside their town. Wasn't that the perfect implementation of the "party town strategy"...?

Shortly after that, the Scandinavians demanded gold, I refused, they declared and I took that town for free...

And the third barb camp was far away down at the isthmus, so that only single barbs arrived at my doorsteps once in a while.
Currently I'm 6 turns from Chivalry. The plan is now to take over the Scandinavians (they are still providing war happiness), then two more civs (the nearest and/or weakest ones), then keep good relations with the remaining two, hoping they can help with research, and finally set up the usual MA for the vote.
I'll try to establish a second core in Scandinavia. However, the GA will probably be triggered during the invasion of Scandinavia as I will need Numidians for the landing?!
Despite being Deity, this game goes quite smooth so far and is highly interesting.

(Originally I thought, "oh no, not the same civ again, how boring..." But it's a completely different game.)
