Welcome to a useful modification to Rise of Nations.
This mod works by overwriting all the race leader names to Computer.
To get the full effect of being anomynous you must name yourself Computer and also your friend(s) needs to as well. If done incorrectly you can get the opposite of this mod!
Locate your "Rise of Nations folder" and move the contents of this files (exclude readme if wanted) to the folder containing Rise of Nations (usually Microsoft games)
Alternatively you could move the contents of this Rise of Nations folder into the installed folder. Included is a full Backup incase you need to revert back (both games)
