Okay, this looks really nice, so I have a few questions:
- Can "civilized" nations turn into tribes if their civilization rating goes down too much?
- Is there a way to stop barbarians from freely accessing and pillaging my lands? I mean, entering someone's territory that freely should have repercussions. If I was Rome and I saw some Germanic army approaching Italy, I should be automatically be at war and fight them off. Pillaging should also result in a casus belli.
- Is there a way to prevent barbarians from settling my low-pop border cities and taking them away? Shouldn't there be a permanent casus belli against them if they do steal my lands?
- What happens to pops who fall victim to barbarians settling in their city? If Saxons settle down in the Colonia Agrippina of Roman Empire, will the citizens remain citizens or will they turn into tribesmen or even slaves? Will they die? Will they flee to a nearby Roman province in the interior?
- Can I recruit tribal units from tribal populations in my civilized nation? Historically, both India and China (and later Rome as Auxilia) made extensive use of tribes within their empire's borders to provide loads of levies to be used in wars, in exchange for imperial protection. They made great source of cheap expendable levies in India and China (who mention them in texts a lot) and Rome used them to provide army support that Rome itself was weak in, like heavy cavalry, horse archers and scouts and later even the loyal Imperial Guard.
- You have said that renegade mercenary leaders can settle down and build their own dynamic nation. Can a dissatisfied clan leave you, take a lot of pops along with them and move to a new location nearby to build a new tribe (dynamic tag), instead of always launching a civil war? Such feature would be awesome.
- Can we pick up pops during migration, especially through raiding?
- Can we resettle non-primary culture pops if we pick them up during migration?
- Will we have an EU4 style "Get off my lawn!" type casus belli to force tribes to migrate away from my civilized borders? One that can emulate the excellent
RTW Barbarian Invasion-inspired feature suggestion someone made a few pages ago.
- Are there any penalties to frequent migration? I mean, EU4 had the "emptied lands" modifier or something like that, which made a province very poor for a decade or two after someone migrated away.
- Will we the players, when as tribals, be allowed to serve a large civilized empire if we settle to their borders (and gain protection and benefits in return)? Most empires were willing to turn them into conditional allies rather than outright annex them.
- As someone asked, if a migrant cohort is defeated, does the horde lose pops associated with it?
- Has the old EU-Rome feature of negotiating with spawned barbarians that occupy your territory, implemented into the game yet?
