Okay! So is this for the players or for an NPC nation? Some concepts for a roman stereotype nation would be:

Heavy Military Emphasis: A career in politics was literally impossible without military experience in the Republic Era, since serving in the army was a requirement of holding office.

No Kings: The Romans hated the concept of monarchy to a comical degree, to the point that IIRC the official title of Caesar was "Dictator for life" and/or "First Citizen." Even mentioning the idea of a "king" was grounds for an assassination or exile.

Faith is Important: The Romans were a militaristic people tempered by strong religious faith. Divine casters would be held in high regard, even if they were not part of the Roman's own pantheon. It was very important to the romans to remain on the good side of the gods.


If you're asking how to kit people out for a roman "Military" aesthetic that would be a bit different though lol

Gladii would be shortswords

The standard Lorica Sementata is splint mail.

The iconic Scutum of the legion is a tower shield.

pilum are just javelins.

A "spatha" the iconic dueling sword would be a longsword.

Romans favored slings over bows in much of their early years.
