An idea for a unique mechanics for Tribes – Tribal Unity

[Me_]

Now that Monarchies, Republics and Theocracies all have a unique mechanics; I think it's time to give one to the tribes as well.

Tribal Unity would be a value used by tribes and steppe nomads. It would replace legitimacy/republican tradition.

Tribal Unity would represent the strength of ties between the various tribes within your realm. Tribal unity would be a value from 0 to 100 and would give the following bonuses at 100:

-15% accepted culture threshold,
+25% religious unity,
+5% discipline.

The idea here is to:

a) give bonuses that none of the other three values give, in order to make it more unique,
b) represent the fact that your tribe is becoming strongly united by giving bonuses to values that are about keeping diverse people together,
c) the discipline bonus is there because tribal unity is rather tied to warfare, as will be explained below.

Tribal Unity would be increased by:

• winning wars,
  
• winning battles (including rebels),
  
• being at peace,
  
• integrating subjects,
  
• 1 – average autonomy (e.g. if your average autonomy is 40% then Tribal Unity would increase by a value based on 60% - whether that would mean 0.6/year or 1.2/year or any other multiplier, I leave to balancing).

It may seem strange that Tribal Unity would be gained through bot wars and peace, but I think that tribes should not be forced to wage wars. Instead, the would have a choice between a slow but steady increase from peace and a faster, but uncertain increase from wars. It would also help vassal tribes, as they would be unable to gain Tribal Unity by declaring wars.

Tribal Unity would be decreased by:

• unfit or underage rulers,
  
• losing wars,
  
• losing battles (including rebels),
  
• overextension,
  
• every time a rebel faction rises in your land (by a fixed amount),
  
• losing forts to rebels.

I think that bad rulers and regencies should not be separate modifiers, since regencies have lower average stats, so having them as separate values would often result in both modifiers being applied at once.

Additionally tribes would be able to declare wars when in regencies.

In 1444 tribes would not start at 100 Tribal Unity, but rather at either 50% or a value calculated based on average autonomy and religious unity (may the Devs choose a better option).

Now for the little twist:

If ever your Tribal Unity drops to 0, your nation would collapse, just like reforming as Mayans – new nations would be released from your country and you would be reduced to a core territory of about 25% of your land. The released tribes would share your government and technology group.

And another twist:

I would suggest adding about 10-20 floating tags that would be used in the collapse to create new, dynamic nations in case there aren't enough possible releases upon collapse.
