With all three of my neighbors eliminated, I now had the whole eastern side of the continent for myself. I decided to stop with the war and start focusing on achieving a victory condition. Since domination, unlike in Civ IV, requires me taking all of my opponents’ capitals, I decided to go for the cultural or diplomatic victory. I basically didn’t care which one it will be, so I went for both. I made a beeline for the UN, while building up cultural buildings in all of my cities.
Thanks to the faith income I had and the religion “elements” I’ve picked, I was now able to buy great artists at an insane rate. I was basically able to stay in a perpetual golden age from this point until the end of the game, so, of course, I decided to go for it. I used the extra income to buy favor with all the city-states and basically dominated every aspect of the game from now on.
Eventually, I researched the required techs to build the UN. I’ve built it around the same time I was able to begin construction of the Utopia project, meaning both of my goal victories were competing against each other. Finally, two turns before the Utopia project was built, a UN vote began and I was forced to vote for someone. I picked the Celts and the game was won.
I’m thinking Civilization V is much, much easier than Civilization IV, so any future games I play will be played on a higher difficulty. In fact, I’ll be raising the difficulty after each game I manage to win. I’ll see where that takes me.
