Ludicrous Barbarians
An insane amount of barbarians will spawn.
4x the number of units will spawn per barbarian raid.
Up to 30 camps allowed per civilization in the game (normal: 3)
The barbs are a lot more aggressive.
Minimum distance for a camp to spawn from your city is now 2 tiles (normal: 7)
The only constellation is that you can get XP from each barbarian until level 6 (normally level 2).
