Observations:
1. World Congress is much disliked and now I know why. You can't really *choose* the resolutions. Sure, you can pick from between two options in each category, but you can't pick the category. Not only does this make Diplomatic Victory more luck-based than it ought to be, but it means you get frustrating situations really early where entire amenities are lost because even the AI allies of yours decided they don't like your luxury.
2. The World War scenario is actually a multiplayer mod, not a single-player scenario, so it cannot be accessed directly from the Scenarios menu. I spent a long time looking for it. I guess the only way to get the achievements is to play it multiplayer and win? Can you simply host a multiplayer scenario with all AI opponents to get them?
3. It's tough to play as Eleanor--the loyalty-based bonus of hers is simply too small scale to really topple enemy capitals, even with spy revolt missions succeeding, Amani and her promotion, etc. I think it's luck-of-the-draw in part, and requires a lot of food to exert truly strong loyalty pressure (along with Bread and Circuses projects). I'd be glad if someone could do a strategy write-up on her. In the meantime I'm contemplating doing a (brief) historical analysis of her for my Civ: Game vs. History thread.
4. The main menu is nicely animated compared to the Rise and Fall menu, but the music remains the same, which is unfortunate.
5. The new civ abilities (esp. Inca and Maori) are so long-winded and require so much analysis.
I am still really annoyed that the loading screen for civs does not include details on the unique unit(s) and unique infrastructure(s), which requires looking at the Civilopedia in-game. Because the Civilopedia....
6. The Civilopedia is STILL inaccessible from the main menu.
7. Games still can end really early (Cultural Victory). No idea what the devs were talking about when making victories maybe take longer. I still haven't played a game where it dragged out to the Future era. Usually long before that, I've won (and this is on Higher Difficulties, like Immortal and Emperor. I no longer do Deity due to how frustrating it is, even when the AI remain easy to defeat).
8. The AI is still really easy to beat. Militarily, they don't seem to focus units effectively enough. I've seen units dawdle around my weakened city without taking it all too many times.
Despite these gripes, I like the expansion so far. The new civs are quite fun to play, even Canada, whose inclusion I deeply resent (still). But Laurier is a fun opponent and he almost makes up for it (much the same as Curtin *almost* makes up for the farce of Australia's inclusion over Maya, Ethiopia, etc). The disasters are neat as well.
