@Artichoker, how would vassalage work out on this map, Maybe switching to that civic to get Charlie to friendly will be an option in the future.
I looked at the save.
Vassalage and Bureaucracy both become stronger in this game due to using an Organized leader, while Nationhood and Free Speech become weaker in comparison. Free Speech, in particular, is weaker in this game due to your choice of using mass workshops instead of cottages. Nationhood remains useful in the short term, probably during a GA, but in the long term provides the worst level of income of all the civics, except for Barbarism.
Looking at the map reveals that there is an absence of Stone on your home continent. Tokugawa and Charlegmagne both possess one Stone each, but neither is willing to trade it. This means that gaining Stone will be very difficult in this game. Oxford University is still worth the hammers, but it will take a bigger investment to get it completed. Because of the lack of discount, delaying it for the hammers may be a viable strategy if you are not in Bureaucracy.
There's certainly an opportunity to get Charlemagne to Friendly by switching to Vassalage and Free Religion. The advantage of doing this is primarily being able to trade techs freely with him. Free Religion is also important because it will improve your relations with all AIs on the other continent, especially Suleiman, who will be a major tech trading partner in the future. With Free Religion, you forfeit the +2 XP bonus of Theocracy, but that bonus can be gained by using Vassalage.
Your window of opportunity of using Vassalage will depend on which kind of victory you pursue. As I see it, there are 3 main options to take:
1) Space Race
This option is very beaker-intensive, so you will want to be in Bureaucracy once you start the final stretch of the tech race. Oxford University will remain a big factor in this phase of the game.
But there is still a window of opportunity to use Vassalage, and that will exist approximately from the time you finish teching Steel, up until the time you finish taking over your home continent (or most of it). During this time, you can focus on gaining the most out of your tech trade opportunities with Charlemagne. Once you've taken over enough land, you should be able to speed past him and the others in the tech race after switching back to Bureaucracy.
Using Free Religion instead of Theocracy will keep your relations with the AIs on the other continent good, but you should probably wait until Elizabeth switches to Free Religion first. In the meantime, you can probably use Organized Religion to make sure you have all essential infrastructure buildings.
2) Domination/Conquest, w/Nuclear Arms
This option is much less beaker-intensive than option 1), and probably no more beaker-intensive than option 3). For this option, you have the same window of opportunity of using Vassalage as in option 1), but this window can be extended even further if you decide to use a rush-buy strategy of military production.
The decision to use Vassalage or Bureaucracy in the final stretch of the game, with this option, will mainly depend on two factors: 1) your choice of location for Wall Street and 2) your level of use of conventional arms in combination with nuclear arms.
With a rush-buy strategy, your science slider will become 0%, greatly reducing the significance of Oxford University. Wall Street becomes much more important at this point in the game. Depending on whether you build Wall Street in the capital or another city (such as a shrine/corp HQ city), Bureaucracy can have more or less potential. Vassalage, on the other hand, depends on the size of your empire. With a large empire, the free unit bonus can become very significant, if you take into account the effect of inflation--which grows large during the later stages of the game.
Also, the +2 XP bonus gives an added benefit to your conventional arms production. With good conventional forces, you can save hammers on nukes when fighting against weaker enemy forces. The most significant advantage here is when producing Marines and Tanks, because you will need to produce these units from scratch. If you choose to produce a good number of Marines and Tanks, then Vassalage will provide added benefit in the +2 XP bonus.
3) Domination/Conquest, w/Conventional Arms
Again, with this option, you have the same window of opportunity of using Vassalage as in option 1), but this window can be extended even further.
As in option 2), your choice of location for Wall Street will directly affect the decision to use Bureaucracy or Vassalage. Building Wall Street in a city other than your capital will make the Bureaucracy bonus less powerful once you move your science slider to 0%.
Unlike nuclear war, conventional war requires large numbers of non-nuclear units. This makes the +2 XP bonus very significant. It also saves you from needing to build the Pentagon, which requires many hammers to build in the first place. Since you are going to war this late, you should definitely consider using your Generals to build military academies instead of settling them. With enough military academies, you can establish a huge production advantage, which gets magnified if you have the +2 XP bonus from Vassalage.
In addition, conventional war leaves captured AI cities largely intact. This has two important results: 1) the population of the captured cities remains high, allowing the free unit bonus of Vassalage to grow faster. 2) the captured cities can act as military production cities, further increasing the value of the +2 XP bonus.
Another thing to consider is that when invading the other continent, attacking Suleiman first will enjoy the added benefit of being free from DOW by Charlemagne, as long as he stays in Vassalage.
For both 2) and 3), you should emphasize using your Great Generals to build military academies, instead of settling them. This means looking for opportunities to trade for Military Science. You should also aim to capture the Kremlin, as this wonder greatly aids using a rush-buy strategy.
. If 3) is on 1) is too in my experience certainly with Liz down and i may get lazy somewhere down the line. My intention is to take Liz down at the beginning of the modern era with cavs/bombers, maybe backed up by infantry then i'll decide if i'm lazy. 
Do either SB or Hannibal have large SoD's?
, i updated the links to gameplay in the first post. Hope they're not gone again by tomorrow.
