I'm not saying it's not harder to win a culture victory compared to pre-patch (It obviously is). I think the thread title is a little misleading - "Freedom tree is now ridiculous" would probably have put people in a better mindset as to what I was attempting to do with the thread.
Victories overall (not just culture, although domination remains a crapshoot depending on what the AI decides to screw up, as usual) feel slower, in no small part thanks to the RA nerf. I don't really think culture fell that much further behind the rest relatively, although it definitely did slide a little.
