I love that no one has won at Immortal difficulty yet, or chopped down enough trees or roads, which would have gone out so quickly with Civ 4 spamming of forests.
Edit: Someone beat it at deity, and only .1% of all players have let the barbarians get one of their cities.
I beat diety a few weeks ago, and noticed it still said 0% the next day when I checked, so even if it says something is 0% completed it doesn't mean no one has done it. I also beat imortal, and beat the game with every leader and all those achievements still showed 0% after.
