Game concept
Foreign Language Limit
From the game's encyclopedia
You can only comfortably remember a set amount of Languages. If you exceed this limit, you will either have to forget a Language or suffer from Stress.
The Language spoken by your Culture does not count towards this limit.
The limit is determined by:
• Everyone has a Base of 1
• Every 5 points of Learning SkillLearning increases it by 1
• The Open-Minded Perk increases it by 2
• The Smooth Operator Perk increases it by 1
• The Language Scholars Dynasty Legacy increases it by 1
