thats why only team vs team has a meaning
ffa is a meaningless system, it cant work
just play on the german league if you dont believe FFAs work. i have a great time in times of civ 4 in FFAs with 6 or more players. sadly at moment we got big trouble to finish games at the moment because of the technically problems which often drop players.
ps.: heres the link the the german league, we welcome international players
