Took the Romans at Classical  Era and kept them .Probably not have done a good use enough of fame that could be obtained through Triumphal Archs after a victory. With a lot of war, and a lot of victories, it could be possible to pillage all of those which are already in place and rebuild them to get more fame each time, but I did that only in the end because this pattern is not good for trade routes. But I'm sure this strategy could lead to something more impressive by an expert player.
