Sorry, I sort of messed up while composing that post. I meant to write "replace religion as dominant factor in diplomacy from around the Industrial era onward". I agree that the effect should not be as high as religion (although it might be worth considering to reduce its impact anyway), but the more important aspect is that the effect of religion should be replaced by ideological motivations in the late game.
As AdrienIer mentioned, the French Revolution is a good case in point for liberal vs. monarchist tension, the Cold War and even WW2 are others. I don't quite get why you consider this a counterexample, especially in light of the fact that before the war the western liberal powers decided not to check the growing influence of fascist states because they hoped to turn them against the supposedly bigger threat of communist Russia.
The animosity between ideologies should probably vary by pairing though, and maybe also by era.
Quick request: Could you please add revision numbers to your posts in the SVN Update Log thread? Sometimes it could be useful to know which update is responsible for changing what, if we want to rewind to a previous version or something.
Oasis shouldn't have culture penalty.
i.e. If Kashgar has 0 culture, it gets no access to oasis next to the city. This makes no sense.
I think those should just get removed. Leoreth said he wasn't happy with them anyway. Also, I believe he mentioned there was going to be some work on the Tarim Basin.
Agreed. How could Vikings settle Vinland in time with this system?
It's still possible, so long as you can research compass in a reasonable timeframe (or better yet, get it from a goody hut). It doesn't take long for culture to cover the whale 2S of Reyjavik, which then gives you access to NA.
What does Compass do for the UHV..?
Yes. Culture penalty notwithstanding, I'm currently also toying with the idea of allowing cottages on oasis tiles and reducing their base yield and making them a little more common.I think those should just get removed.
