How are diplo victories easy... no one ever votes for me, they vote for themselves
they're not easy, that's what's fun! some of my most challenging games have been OCC diplo victory. my own votes count for diddly squat, if nobody votes for me i'm dead in the water. not to mention that if i don't build the UN i can't ever capture it, so there goes that plan. hell of a rush when it works tho
Also as someone already stated, run theology if your that afraid of the little palace, in order for a diplo victory to even be an option the religion has to be in every civilization in the world.. if it's not in any of your cities the option will never appear.
that's not a guarantee tho. spies can't spread religion directly. but they can influence civic changes. for example, in my current game i changed gilgamesh (who had the AP religion) to free religion with a spy, so that he was a voting member not a full member, and therefore i could hold votes to "assign his cities" to me, since he had a zillion troops in them. at 86% my culture they had no chance of revolt! that was driving me crazy, i wasn't in the mood for gunfire at that time, so i tried something different. it worked, he didn't defy the votes, i got 2 so far. ones i'd rather have razed and settled one tile over, but that just was not going to happen, so i took what i could get.
same game, hammurabi was in theocracy with no islamic (AP religion) cities. he'd had one, but i'd culture flipped it, so he'd changed from voting member to non-member and i lost the "assign city" vote for his holdings. almost all of his cities were safely buddhist, so i put him into OR by a spy and spread islam (my AP religion) to one city so that then he was then a non-voting member and i could vote to assign his cities. he veto'd that vote, but that meant i got to watch that city celebrate unhappiness because the world hated him, fun fun! my goal wasn't to enable the diplomatic victory option, i wanted the game to continue to see what would happen, but it would have given me the option to hold the vote.
i did
not know before reading this thread that both the AP and the UN can be active at the same time, if the AP builder/holder doesn't know mass media. i suppose that does follow standard civ4 rules of "you discovering tech" obsoleting X rather than the old way of "mystery civ discovers tech and your life goes downhill", and i usually 100% prefer the civ4 way. but this case seems completely illogical. once i get over the frustration, i do actually enjoy seeing the computer beat me, if i knew i'd win all the time i'd get bored. but IMO the whole AP thing just isn't balanced atm it feels "cheap" to me, given my bias to favor diplo wins where you do need votes from others to win, and don't just have enough pop yourself. #1 definitely for all wins, i certainly do think that people should play games that are fun for them, and my biases don't matter one bit...your game, your free time, your rules, i have nothing to do with it since you play for yourself! just qualifying why my opinion on the whole AP victory under that "get that last civ one city so you can hold the vote and declare yourself da winnah" method to be cheap, rather than overpowered.
