Thanks for that link! It looks like there are two quotes for most techs. That’s a nice touch.
This expansion has grabbed me more than vanilla Civ 6. I especially like loyalty, eras, the new golden/dark ages, and alliances, which really improve the diplomatic game. I don’t have much experience with emergencies yet.
I think Governors are under-developed. I like the idea, but the implementation in Endless Space 2 is better. I’d add more upside/downside pairs to the Governors, and make their experience trees a bit more detailed. I’d make it more intuitive to swap them in and out. I like that ES2 lets you assign governors to either settlements or military units. For immersion, I’d certainly add more than 7 governor portraits and names that every Civ uses. Yeah, if each Civ gets a unique slate of governors, that’s a lot more work, but they have time to do that for the next expansion.
The diplomatic AI in general seems better to me. It’s mildly annoying to be the occasional target of “formal” joint declarations of war, but my impression is that the AIs are trading DOWs for goodies, so I can live with it. On the other hand, the alliances actually mean something now. The combat AI is still flawed, but even that has seen some incremental improvements: the AI can and does take walled cities, and it’s better about both beelining toward cities and picking off wounded units. The economic-development AI seems slightly better too. None of these AI improvements will change the minds of those for whom AI is paramount, but the net result for me is a tenser, more challenging game.
