Today, I haven't built not single one coal plant, nuclear plant, or hydro plant. Not a single one. Just Three Georges Damn. And the rest of the world is in middle ages.
So, Izzy tried to attack me
An, just so it happens I have nuke. One nuke. I will repeat: ONE
And I "destroyed" her holly city (who could resist

) cause I didn't want to invade one more continent.
So, that ONE nuke, and global warming strikes. Random parts of my land turned into desert. Tundra near river turned into Sahara style desert
I naturally won (first cultural on noble

), but this really really sucks.
