Carthage must be busy with Rome, because they aren't attacking me anymore.
330- Suddenly realize I haven't traded maps with Zulus, so I do so.
310- Learn The Republic, and revolt immediately. I only get a 3 turn Anarchy!! Woohoo!
Make peace with Carthage, thus breaking the alliance. Bah, I don't care, I have good trading

guarded by a Hoplite, and they trigger my Golden Age! Hooray!

480- Egypt offers to trade us some Incense for our Spices. I take the trade.
Monotheism learned. Now researching Theology.

630- Golden Age ends.
640- Education learned, now researchin Astronomy.
650- Zulus demand Theology. I refuse, and surprisingly they don't declare war.
Leonardo's Workshop built in Athens!

This as good a time as any for another screenshot:
780- Astronomy learned. Now researching Banking.
Sending some workers to the colony(Ephesus) to hook up some Dyes.
790- Trade Education to Carthage for Gunpowder.
We have no Saltpeter. Actually, there's one source just across the border in Roman lands.
I'll rush some culture in Mycenae to try to grab that tile.
840- Major culture war between Mycenae and Antium. An investigation of Antium reveals it has slightly
more culture. I rush a Colosseum to compensate.
880- Trade Astronomy to Egypt for several things, but mainly Music Theory and some GPT.
890- Mycenae finally wins the culture war! Immediately upgrade all Hoplites to Muskets.
940- Egypt declares war on us!!
I have to pay a LOT, but I get Carthage to ally with me against Egypt.
980- Zulus demand Spices. I refuse and they back down just like last time.
1000- Egypt captures one of my catapults, but then Carthage captures it so I can't get it back
1020- Build Copernicus' Observatory in Sparta.
Meanwhile, I gather Catapults in Knossos for an attack on Egypt.
1040- Egypt unfortunately catches on to my plan to pillage their Iron, and they kill my pillaging Musket.
He survived like 6 turns in to their territory, but Egypt killed him just as he reached their Iron.
1050- Oh ****!! Egypt gets the Romans to declare war on me!
1070- Hmm, forget trying to attack Egypt. I need to focus totally on defense.
1080- Rome pillages my Saltpeter. Oh well, at least now I can build cheaper Hoplites.
1100- The RNG cheats horribly as Egyptian Knights kill all my Muskets in Knossos with little effort.
I quit.
YOU [expletive] CHEATING RNG!!!

Also, Rome captures Mycenae.
Again, I QUIT!!
At this point, I get a Retirement loss because I quit the game.
Summary: Musketmen fortified behind walls are apparently defenseless against Knights.
Wow, just wow. I haven't had a game suddenly go so wrong since I left Regent level. Back then I often
had a problem with AIs suddenly sneak-attaking me at the worst possible moment. As I got better at Civ
the problem just seemed to go away. And then now, many months later Egypt catches me with my pants down.
I can only conclude that the variant rules had something to do with this. My military was fairly small.
I kept at least two Muskets in each city, and three in some. In a normal game, I would've had a half-decent
force of offensive units sitting around just in case of a war. Without such a force now, I was totally
immasculated when it came to warfare. I pumped out a LOT of Muskets and Catapults after the war started,
but they did me little good. Catapults really suck (I wish this had been on Conquests so I could've built
Trebuchets instead), and I only ever managed to shave one or two hit points off of a few Knights.
The Muskets should've done better, though. I managed to actually attack some red-lined Knights and kill them.
Mostly they stayed on defense, though. That's where the RNG screwed me. Three Egyptian Knights attack
Knossos, moments later I have three dead Musketmen. Same with Rome up in Mycenae. Their MDIs destroyed my
Muskets up there as well. Both cities had Walls.
This game was *probably* salvageable, but it would take much more effort and time than I can give. I could
have made peace with Egypt, thus breaking the alliance with Carthage and destroying what little reputation I
had left. Rome I couldn't make peace with, but I could have held against them in my stronger core cities, maybe.
But once I had peace, I'd be much weaker, and susceptible to any power-hungry despot who wanted my land.
I'm betting that it wouldn't have been long before Carthage set his eyes on capturing my Spices.
I can't really foresee a win for me resulting from this situation, so I retire.
