Hi:
I have noticed that the .map file has been downloaded more times than the .rgb file. Both files are necessary to play with the map.
The .rgb file is the graphic image of the map. The .map file is a text file that informs the game of the location of provinces, names of provinces, neighbor connections, etc.
(Maybe some folks just wanted extra copies of the .map file, or maybe spider bots are downloading only the first file.

)
