I think that historically lorica segmentata late legionary cohorts appeared after the game timeline ends.
That would be interesting to know for sure. One of the reasons, but not the only one I'm sure, that all heroic land markers seem to end up going in favor of the Romans whenever they are involved. Yes, the Roman army was one of the best, but they didn't win every battle

Also forgot to mention that i reduce intial treasury for the Romans, the level and population of all Roman towns as well as their starting army. Also no Roman faction starts with a port.
I'm not sure I want to go that far, but taking a clue from your lead, I might give the Romans a port only for their capital at the start.

As to unit size changes, maybe later. A little at a time What directory is used to alter movement speeds? That's a good idea to make more realistic and eliminate those idiotic scenes during battle where infantry are running nearly as fast as horses

Regarding Carthage....what's the benefit of reducing Iberian infantry unit size from 80 to 60?

I've looked thru that topic before. Those guys seem to know the game quite well. However, I do like RTW for an occasional game (when I get tired of STW!) but not enough to do such extensive modding. There is a lot of excellent material there, though......
