Good game
@Northerner . I think you were at a disadvantage, since you had more coastline, and with the current rules marines and warships are effectively siege units that can strike without "staging" or presenting themselves as vulnerable to counter attack if the assault fails.
I hereby resign control of the French. From my perspective, anyone can examine the French saved games. However, you may want to hold off on the last few months if the plan is to leave the French Empire intact as an AI rogue empire, or something. I'm willing to answer any questions about my choices/gameplay that anyone might have.
I'm willing to take over the independents, I won't be offended if that becomes impractical because territories have to be given to them to balance out the game. "Reset" the game however seems likely to give the other four powers the most enjoyable time. If there is a space for me to play in that new game, then I'm happy to play. If not, I don't mind quitting and being an observer.
This is my strategy/diplomacy, at least the way I remember it (I didn't look through old PMs or anything).
Early game, I was concerned about the possibility of war with Germany or Great Britain. For Great Britain, I was hoping I'd be able to avoid a war (even with some concessions) until after steel warships, since that tech essentially renders all older ships obsolete, so I wouldn't have to do a major naval buildup to be able to threaten British trade. This kind of conflicted with my desire to get closer to Russia, in order to have a counterweight against the Germans. The Russians seemed to be looking to France to be able to offer naval assistance against the British, but I didn't really want to commit to that kind of friendship/alliance, based on my strong desire to keep the peace with Great Britain. I figured I'd be friendly, and rely on the fact that Russia probably wouldn't want Germany to take over western Europe, even if France and Russia weren't full allies.
Regarding America, I was very keen to maintain trading rights throughout the whole game. Since America was sticking to its own hemisphere, all that really meant was not trying to colonize Latin America. This wasn't a huge burden, since for most of the game, there were colonies available in the old world. Until I established a railroad across Africa, I sent many ships across the Pacific Ocean and then over Panama, with the permission of the U.S. Until that point, the U.S. could have done me very serious harm through an embargo. At about that time, I had also established other options for trade. Australia and New Zealand (and the Falklands) were a substantial alternative, but I could have done domestic trading off the west coast of Africa also.
There was a point when Germany wanted to take over Milan (or was it all of Italy?). I asked the British if they would stand by their guarantee of independence, and said that if so, the French would support them up to and including armed conflict. If the British refused, I would have tried to make a deal with Germany to split up Italy and Spain. I figured that even if France and Germany got a comparable number of cities, French territory in Europe would move from ~1/5 the number of German cities to ~1/3, so my ability to resist German invasion would be improved.
At that point, France and Britain discussed what would happen if there was a German Russian alliance and we got into a war. At the time, it looked like such a war would be difficult to win, but that we could probably strangle enemy trade enough to win by eventually having superior technology.
Trade wise, my policy was to rush Iron Ore Mfg Goods every turn, where available. (Eventually, I ended up being rich enough to rush everything everywhere, but this was before that.) I figured that rushing an Mfg Goods from scratch was less than its delivery bonus, so I should get one every chance I got. Since most of these mines were in the Far East, that left the area with few troops and very important economically to the French Empire. When I used marines to capture Xiamen, and the Japanese (or was it Russians?) were nearby, I figured it was best to give back the city (we ended up signing a bit of a demarcation treaty), and hopefully make war less likely for a while.
As French power grew and German power didn't, I came to see Germany as a sort of buffer region between France and Russia. In the event of Russian invasion, I would have, at the very least, given Germany a lot of money to rush troops for the defence. I didn't attack Germany in part because I figured the Russians might have had a similar policy in mind, and in part because it didn't seem like "good manners" to push around a smaller player too much. There were times when I considered bullying Germany into allowing French troops to cross German territory in order to attack Russia. I don't remember if these musings were serious, or just thoughts about what could be done.
After I finished the mass railroad in Africa, I contacted Britain and Russia about getting permission to build a mass railroad to the Far East. If Britain agreed, I would have been willing to go to war with Russia to force the concession. I suppose that would have been a good limited conflict. The stakes would have been serious for Russia, but not existential. I figured Russia might refuse the Railroad, since it would speed up everyone's trade who used it, but Russia wasn't in that much of a position to use it. Ultimately, the Uganda Crisis happened instead. I briefly floated the notion of Britain and France allying against the world, but Northerner decided to provoke the Uganda Crisis instead, and I quickly saw that was probably for the best.
When Britain had a disagreement with Germany about some railroad in South Africa, I figured I could use that to as a means to protect my southern flank. So I offered some money (of which I had plenty) to Germany to build up the Boer territory defences. Eventually, this became a more general partnership, where I offered funds to be used even in Germany (which was to shortly join my war against Britain). I think this helped a lot, since having Germany on my side allowed me to have basically no troops defend the French/German border.
I think it was shortly before Christmas when I realized that I was in a good position for a general war against Britain, and that the window was likely to close in a few turns (at least as far as technology was concerned). I remember a turn where I thought it would be good to declare war, but I just didn't want to that turn. I originally built up the forces in Pondicherry "just in case" the crisis with Britain spilled over into a general war, so that the city could cause lots of casualties to the British. Eventually, I realized there was a decent chance to conquer part of India before the subcontinent could be mobilized for war.
I think that's about all of my thoughts about my Presidency of France.
