Yeah the CS are overall just easier to get and I think that a little adjustment to quest rewards and that ideology are definitely warranted. Yeah the AI doesn't seem smart enough to not vote against the guy with the most delegates for host or World Leader.
I've not had this, at least on larger maps - with so many CSes and so little gold, relatively speaking, you have to rely much more on CS quests, and it's not easy to manage that with all CSes.
Also, in my multi-civ game, so far in all elections for host and world leader, each civ has only voted for itself, so yes everyone's voted against the civ with the most delegates.
What they should probably do is make it that you can't vote against an AI for host or Leader if you have a Dof (so playing diplomatically is actually a plus) but that AI's that truly hate you will try to group up against you diplomatically to elect a less powerful host.
Why would it be a plus to discourage forming DoFs, as this would do, since it will never be in your interests to vote for an AI for host or DoF, and abstaining would still increase their chances?
One limitation I have seen is that the AI doesn't know how to use the "please vote for me" diplomatic option, or possibly doesn't know how to use diplomats. Certainly I've never seen an AI ask me for my vote (except in one case where I asked what they wanted for a deal, and Nebby threw in "vote Nay on science funding". Which did make me wonder if he really understood the point of playing as Babylon.)
3) I don't know if this is just me, but it doesn't seem the AI does war at all (which it shouldn't be as random as before but it should still happen) or use spies. Within my 400+ game, I saw no coups of City-States and I turned my spy defending my capital into a diplomat because nobody was trying to take my techs even though I was on top of tech.
I had very few wars until the modern era (Emperor), but ideology really seems to define this. Since adopting Freedom I've been at war with the neighbouring Netherlands (Order) and denounced by every other non-Freedom civ (including former friends Babylon and Assyria). Currently in an alliance with all four other "native" Freedom civs (to my surprise - since I didn't know that could happen - I got a notification indicating that a revolution had forced Shaka to adopt Freedom, but by now nearly everyone hates him).
No, the AI doesn't seem to use spies. I'm doing it a lot less, since diplomats really are valuable (I think spies should now definitely scale with map size - on a huge map the extra options but no extra spies make them very limiting), however I'm also actually making use of the diplomat option in a way the AI seems unable to. If it can't horse-trade for votes (with or without literally exchanging horses for votes), it should use spies more. Though I have had one tech-steal and there was one CS coup.
Also, I think possible intrigue should now include a possibility of learning a civ's voting intent, even if you don't have a diplomat (and if you do you can only figure it out for specific civs by the specific diplomats you have and the number of delegates in those civs, since the Congress tooltip won't tell you which civ is voting for/against a proposal).
24) The AI needs to chill the hell out with the settler-spamming
I've seen an awful lot of inexplicable archaeologist spamming, even with no antiquity sites available or with some of the accessible ones unexploited. Bizarre waste of AI resources.
21) I expected the vote for a new host to be a resolution that had to be proposed. This would play off the proposal given by the host as a kind of chicken game to obtain your much-wanted resolution just before being dethroned. Instead it is a game of hot potato.
How it's proposed is less important than the fact that it gives you no options to ask for votes for/against. So far the trade-for-vote idea is a good concept but appears not to work or be very relevant in practice.
22) World leader vote. Broken system as-is.
Should probably use the Civ IV system (i.e. two civs with largest number of votes only get to be voted for - which seems to be the way the rest of the resolutions do in fact work).
