Alright, after a conversation with Bercor and reading many threads about AI expansion with other mods, I decided to make this so we can dictate which factions need to expand where. Every faction needs to expand somewhere, the game is not built for a faction to turtle. It's total war and every faction is trying to rule the world. This can also be tied into certain victory conditions for factions.
I'll go ahead and state my thesis for each faction and their expansion routes.
Rome - They need to want to expand everywhere, beginning with Sicily. With a land bridge between Italy and Sicily, this is possible. In RTH, Philadelphos has Rome at War with Epirus and almost always Rome expands into Sicily and ends up taking it. They then need to also find a way to get into Gaul eventually. Basically, we do not want Rome getting stuck and stop expanding.
Carthage - Should be focused on Sicily and Spain, eventually putting their focus on Italy. Yes they need to be semi concerned with Africa and the Numidians, but Sicily should be of main importance. I wonder if there is a script where if Carthage loses it's last city in Sicily that they automatically turn their focus to Spain and start expanding there? Maybe that's too predictable?
Diadochi Factions - Should all want to recreate Alexander's Empire as Well as own Greek Colonies
Gauls/Germans/Dacians - Should want to control most of Central Europe, Italy, Spain and Greece
Sarmatians - Should want to control most of northern Europe, Eurasia, Bactria/India and even Persia
Iberians - Control Spain and North Africa as well as Gaul?
Numidians - All of Africa, Arabia, Spain
Parthia/Armenia - Old Persian Empire
Pontus - Black Sea and Asia Minor Empire
Greek Cities/Greek States - All of Greece along with it's colonies
Independent Peoples - Either nothing or the entire world
