In regular BtS barbarians are a continuous but graded threat.
In C2C we don't have the grace periods provided by 1 & 2 as wild animals and Neanderthals start spawning straight away. Neanderthals can be turned of completely to partially return the flavor of BtS but that has other problems.
In BtS the threat from barbarians to your nation has three levels
In C2C 1 and 2 are provided by the Neanderthals almost exclusively with 3 being the aim of the barbarian cities with minor help from the events. This means that if you have Neanderthals off you don't see any barbarians until they are strong enough to destroy your nation!
I don't think the spawn rate for these barbarians is determined by game difficulty but it should be.
I would like to see us
- there is a 10 turn grace period so you can move your settler around to find a good place to settle.
- wild animals that can't enter your territory spawn allowing you time to build up your first city a bit and build a small army. They also provide a small limit to exploration.
- later some human barbarian units spawn these can enter your territory threatening your workers and improvements. They also provide a much bigger limit to exploration as they can easily kill your scouts.
- later barbarian cities spawn
- events start happening that provide invasions and pirates

- pillaging parties (2 above)
- looting parties (2 above)
- city destroying armies

I would like to see us
- reintroduce the grace period, (getting rid of dates would make this much easier)
- reinstate the small barbarian parties in part by having the barbarian cities go back to mostly making raiding style parties and by increasing the invasion events.
- change the Great Wall so that it stops the raiding parties but not the invading armies.
- we should also add back in the slave (and like) revolts and add a few bandit events - assuming we have fixed the Great Wall for this already.

and maybe barbarian land.
. If it is in the Python it is just up to me at the moment.
