I spent a while looking around to see if there was anything major I wanted to change, but basically everything seemed fine. Almost all I had to do in my turns was kill units, trying hard not to lose anything. At this point, there just isn't much to do in managing the cities.
The only thing I noticed was that we had some spare resources, so I sold them to Egypt and Greece. I also noticed that Istanbul was building a monastery- was there some reason for that? I think we have enough social policies already.
I have to admit, janissaries are pretty cool. I moved this one back off the hill, hoping that Siam would put a unit on the hill next turn. They did, and so the janissary retook the hill, and in the process healed himself.
I wasn't sure what to do, so I turned to our brilliant advisors for inspiration. Turns out that, despite all our units, we're still defenseless!
turn 1: Alex asks us to stop settling near him, but I refuse.
Siam launches a major attack across the river. I can't kill all these units, so I do what I can and then retreat from Akhetatan.
In the west, I was able to take Ravenna. This city changed hands about 6 times during my turns.
Also we get news this turn that Siam has entered the industrial era! That's not good. I never saw any artillery from him though, so he probably got biology.
Turn 2:I retook Ravenna (killing another musketeer instead- cities are a death trap in this game!). Metallurgy finishes, and I choose rifling next. Edirne finished its armory, so I changed Istanbul and Edirne so they can finish a Janissary before rifling comes in. I retake Akhetatan from Siam, and found Yukon in the northern tundra.
turn 3:Take ravenna once again, and clear out all the units around Akhatan, while the wounded units heal.
turn 4:I lost my first unit this turn

Napoleon moved up aggressively, and killed a knight which was almost at full HP in one hit. Units are so fragile on open terrain! Anyway I retake Ravenna once more, and buy a jannissary in Edirne.
turn 5:By some miracle, Ravenna actually held this time! Actually I would have preferred to lose it, so I could kill another french unit inside. I buy a sipahi to replace the knight I lost, mostly just because I wanted to try it out.
Look at the situation here against Siam:
I can't see any units, so it seems like I could probably advance and take that city. However... I'm worried that he could bring up units from the road behind the city, and kill our units as they cross the river. I really wasn't sure what to do here. It's just so hard to attack across a river in this game! In civ 4 I wouldn't hesitate to push forward and take the city, but in this game it's just way too easy to be ambushed by defending units. I decided to play it safe, and hold position until we get rifling.
Turn 6: Monty is hostile with us once again, and he's #1 in units now. We need to guard against him as well. I sent 2 janissaries to the border there, but we'll probably want more untis there.
Turn 7: Still can't see any units from Siam. On the other side, I'm enjoying the ridiculous 5 move of the Sipahi. I gave it sentry, so it's an excellent scout.
turn 8: more french forces attack Cumae, so I move a knight there to defend. Byzantium finished a university, so I switched it to using 3 scientists. It's now a science city.
Turn 9: Golden age begins. France once again fails to retake Ravenna. Look at all these units they have!
Siam has apparently given up on Akhetatan, and sent elephants north. I killed one with a Janissary.
Turn 10: rifling finishes, as do 2 more Janissaries. Fertilizer due in 6 turns, and then we can bulb dynamite. Here's our demographics- massively inflated by the golden age, but it's nice to be #1.
I feel like, despite all the units that I killed, I still didn't really accomplish anything. It was just treading water. I guess it's OK though. With riflemen Janissaries, and artillery, we should be able to really start pushing forward. SevenSpirits can decide whether he wants to attack Siam now, or wait until artillery. We might be able to attack his northern city, too. France has an annoying large number of units, but I don't think he can really hurt us. Monty might be more dangerous, since he's right next to Istanbul.
