Yes, I successfully finished a GotM for Civ 4!
Really don't even want to think about when I last finished one (successfully since my last tries were getting used to the thing again

).
As expected I finished my conquest of the world soon, but not soon enough. I conquered the last city at 1515 AD after searching it for about 10 turns. It was tucked away in the corner of the America's.
I liked the map, at first didn't even notice it was an earth map

, it was fun to play without metals although I think it made the keshiks too strong.
Two points to be learned: whip more + believe in your strength (so attack sooner).
