OMG, I just found something new in Civ V. I don't think I've even seen a walkthrough on this one.
Aggressive Cultural Victory with Assyria (Brave New World).
Continents map.
- Destroy every other civ in your continent. Completely destroy them, you don't want any refugees left to spread the word.
- Raze everything except the capitals or cities with wonders, and don't rebuild. This causes the game to keep spawning barbarians, which you can farm for culture points. Only destroy camps when City-States beg you, you're effectively running a protection racket., every CS in the continent will soon be your ally, and it won't cost you anything. And a new camp will appear ten rounds later.
- Once you've wiped out your neighbours, go exploring. Every remaining Civ will happily be your friend, exchange luxuries, and open up their borders to you, because they don't know what an evil bastard you were.
- If any other civ has the temerity to think they can settle in your not-quite-a-virgin-there-used-to-be-a-city-there territory, destroy them, then go to their home country and take out their capital, just to discourage any further attempts.
There were three civs left out of an initial eight when it ended. Assur - tourist capital of the world.
