Martinus
Emperor
I guess the reference to Rome is a combination of several factors, some of them already mentioned:
- a slight boost to wide empires (and Rome has the most wide-empire-friendly UA of all civs),
- a good possibility of winning a cultural victory while being wide and aggressive (in fact they referred to Rome before as a historical example of winning a cultural victory the BNW-way, by capturing great works from other civs and then dominating them with your culture), and
- caravans could be used to boost production in the capital, and the more buildings are built in Rome, the more powerful the Roman UA becomes.
