Discovered the internet in 1941, pretty much a must for a cultural victory.
Austria was pretty much going on world domination starting by swallowing up like 6 city states then going after everyone else in her continent. She had like 80% more score than me and I was in second place near the end.
Here's Paris, generating 590 culture a turn and the main tourism generator. I think I lost a world wonder or two in the process but I almost got the ones I could. Sydney Opera House needs a coastal city so that's out.
So what's the side effects of having a lot of tourism? A lot of unhappiness for everyone not on the same ideology. If I hadn't had so much culture, I definitely would have incurred a ton of happiness since everyone was with Order. Austria still got like -31 unhappiness, which is definitely affected by the number of cities she had.
Just the scores, cities, and my social policies near the end.
