Tip, visit the graphics card page (there is a link next to the FPS number) and compare your graphics card to it to give you a personal point of reference.
In a scenario there are Major Factions and Minor Factions. These are usually the Roman civil war factions plus occasional foreign factions that play a key role, for example Parthia in Scenario 03.
But in general, is this a Roman-centered mod, so dont expect too much foreign factions to be playable. These represent lesser states that did play some role in the Roman conflict, for example as Roman allies, as victims to Roman expansions, or as a nuisance you have to deal with. Factional Moral and Dissolution Each faction has a certain Factional Moral Index.
This means it will surrender all its possessions to another faction (Roman faction usually surrender to other Roman factions whereas foreign factions usually surrender to the slaves).
As a result, you dont have to conquer each village and kill every family member of an opposing faction.
The Periods define things like city development, Romanization, and most importantly recruitment.
The major change is from Period 2 to Period 3 (Post-Augustan).
