Speak for yourself. Peaceful victories are still entirely possible. But bear in mind that they shouldn't always be possible - if the game is an approximately level playing field and if there are say 8 players in the game, then you should only have a 1 in 8 chance of winning. If you can always win by your victory of choice then the game is broken - it's not even a game, just a sandbox for playing in.We'll have to see, more games need to be played, but I'm am starting to get the horrible feeling that no-one has realised the tech ramifications of the Blake AI inspired changes, in that at Monarch (probably even Prince now) and above, a peaceful path to victory is all but obsolete.
The easy way to get a peaceful victory is to bribe the thug AI's onto the builder AI's to keep everyone busy (ie manipulate religion). Skillfull use of wonders and great people is also key, but you sort of need marble or stone and a suitable start point (2.08 AI's aren't very wonder happy, altough my newer AI will chop wonders). Trade is extremely important now that the AI grows bigger cities, compass is an awesomely valuable tech since the AI undervalues it.
Basically, a peaceful victory is now a puppetmaster victory, which is probably how it should be, the idea of being able to win without investing in diplomacy or war is a bit wrong.
