I picked up from my last game by consolidating my gains and sending out some settlers to the east. Unfortunately Joao had REX'ed pretty far west so I was only able to squeeze in another 2-3 cities before I ran up against his borders. I then hunkered down and decided to commit to a medieval war. Qin was tiny and Gilgamesh didn't have much production either. I figured if I struck swiftly, I'd be able to take them out before they would become too problematic. Also, the eastern region of Joao/Toku/Boudica were Buddhist buddies so there wasn't much point in trying to stir up action over there.
So I teched CS, then went towards machinery followed by engineering -- guilds. I then went gunpowder in case I needed it before I went back to paper -- education. Joao by this time had been caught up in an unfortunate war so he was teching military techs.
On the war front during this time, I thought no wars would happen to the east but Boudica declared on Joao, then bribed Toku to join in. That war went on for a while. After that, Toku declared on Boudica. Joao also dogpiled against Boudica, ultimately vassalizing her towards the end of this set.
To the west (my area), I declared on Qin once I had enough trebs to tear down castles in 3-4 turns.
He only had two cities left so it didn't take too long to take him out, but he did build one on a hill with CG2 LB which wasn't very fun to dislodge. However I did pick up Chichen Itza and the GLighthouse for my troubles:
I then healed my troops and headed north, invading yet another protective civ. Gilgamesh had quite a lot of troops as he's a warmonger by nature but he didn't have anywhere to burn his excess troops on. As a result, I had to take out lots of units to take his cities. He also had the SoZ in Uruk, which caused some serious problems. After I had taken 2 cities, WW had shot up to around 600, and it was well over 1000 when I finally took Uruk. This is when creative helped - I built theaters and colosseums in all of my unhappy cities and pushed the slider to 20%. This generated 5

, which helped to offset the 12

that some of my cities were seeing. I also resigned myself to losing some pop - I just needed to hurry along and capture Uruk to quell the WW.
By the time I took Gilgamesh's capital, Toku was at peace with Boudica. As a result, he decided to take Gilgamesh as his vassal, even though he doesn't have astronomy and doesn't have OB with Joao

(This is also the reason that boudica stayed independent for so long - Joao couldn't send his troops to attack her core). Anyways, Gilgamesh didn't put up much of a fight after I captured Uruk as his remaining cities were very production poor.
I played on a few more turns after that so that I could tech up to rifling before I decide what to do next. Boudica built the AP in one of her cities but Toku managed to capture that city. As a result, the most recent AP voting was between Toku (who's hated by everyone for being Hindu at this point) and me. Since Joao and Boudica were both pleased/friendly with me, I handily won the voting. So I could definitely take an AP victory at this point. Or I could continue massing my army and just declare on Joao and drive eastward. Toku can't reach me so I'm not too worried that I'm still at war with him.
