SIP, Bibracte built worker, warrior, WB, worker, warrior, settler, settler, settler, worker, WB, settler with a whipped galley in between to protect seafood, warrior, library
new cities built worker, monument, then what was needed - workboar, warrior, granary, library
Research went: Agriculture, Wheel, Fishing, Mining, BW, Potery, Sailing, Writing, Aesthetics, IW with some switching to alphabet, as the AI didnt research alphabet and i was impatient. but i traded for alpha with pacal for aesthetics at the end anyway. so it was just wasting turns
then currency, CoL and some trading to fill the priesthood, masonry, monarchy etc.
the research polytheism, literature and built the great library, construction, civil service
I had small troubles with barbs, and had to defend with warriors against an axeman, but after that it was fine.
I didnt build any wonders, only later GL and Taj Mahal and national epic in bibracte and Heroic Epic and West point (while I was waiting for rifling) in Gergovia
barb troubles:
some stupid moves followed, like having gergovia undeveloped for so long and having it building settler at size 1... Bibracte should be growing to higher size and not building a settler...
50BC:
Researched HBR and built stables everywhere, as I was planning long time either cuirasier or cavalry war. Then researched music, liberalism for military tradition (1230 AD) and research to rifling. traded for some tech like feudalism, but tried not to give away music or military tradition. GA from music used for golden age, two scientist born used for double bulbing education.
I switched to Judaism sometimes later (around 850 AD), to keep Roosevelt, Hamurabi and Sury pleased or later even Friendly. Pacal declared and attacked with one catapult.

I took one city with elephants and signed peace for money. Then he declared again when I had some cuirasiers ready, and reserched to rifling. When I started building cavalry, it was virtually war until the domination. First Pacal, then Roosvelt as he was teching quite well, probably because he had the Great Lighthouse. Then Hamurabi, then Sury.
Good thing was, Sitting Bull was in war with Tokugawa for a long time, Toku vassalised to Sury, and SB and Sury were fighting all the time then. When I attacked Sury, I managed to shred two of his huge stacks in SB territory, so it was quite easy then.
I felt kind of bad declaring on Roosevelt and Hamurabi when they were Friendly of Pleased towards me.
For some reason, only Roosevelt was getting close to Rifling, but that was just before I killed him. All the others didnt research it, even though they had Replacable Parts researchable for so long. That was quite lucky for me, still I dont understand it. i was also lucky that nobody peace vassaled to anybody when i was conquering them. I normally play with vassal states off, so I am not very familiar with it.
