I think you will find in a poll that more people care about the world map mod than a full conversion mod like victoria.
The reason for me is simple. When I watched the previews of ETW it kept showing generals looking at a map of the world. We all figured if it was in the era of empire that it would be a global map. Imagine my shock when most of south america half of asia and most of africa was missing with no australia at all. I was appalled. So were many other players.
