What to you are the essential things for running a game in a post fallen roman empire? Do you have a list of things that are needed to give it a certain feel?
Technically, that's "late antiquity" or even more colloquially "the Dark Ages", which has a completely different feel to classical antiquity several centuries before.
There are some basic things to do, like changing the standard equipment list - plate armour and things like two-handed swords don't exist. Are you going for a straight historical game, or just something vaguely inspired by history?
Lamellar, banded and plate armor are only available in Class I markets (e.g. the equivalent of Byzantium).
Two-handed swords and crossbows are not available in any markets.
Books are considerably more expensive and valuable. They cost twice as much in Class I markets, three times in Class II, four times in Class III, five times in Class IV, six times in Class V, and are absolutely unavailable in Class VI.
Reduce the range of all trade routes between settlements by half (land) and one-quarter (water). Trade has largely collapsed. Demand modifiers will be sharply disparate between major settlements, which no longer are able to trade with each other.
Make heavy use of Special Treasure in lieu of coin treasure. Coin was increasingly scarce and goods were used in barter instead.
Double the number of mercenaries.

More vaguely inspired by history.
Some suggestions:
