1) Slave labor:
(I'm not sure how this should/could be implemented. Maybe something similar to ruin/relic income)
Factions that get this are:
For Shiekah. Because of brain washing.
For Lybrynna. Because of Tokya slaves and/or other possible slaves.
For the Stalfos. Because of mindless workers.
Maybe for the Gohma too. For the same reason as the Stalfos.
2) Religious Donations:
(Given By the masses. I guess it would work like; X chance of getting X amount per X time/turn.)
Factions that get this are:
The Wizzrobes would have this. As well as the Darknuts.
They both have quite a fallowing. And are a Religious Organization. Whether they admit it or not.
Not sure who else gets this though. Maybe the Kingdom of Hyrule and Fairies of Tarm. But I'm not sure.
3) Raiding income:
(If you attack a settlement and/or army. Whether you win or retreat, You get X chance of getting X amount per X# of units doing the attack. But the raid fails if you have no troops alive after battle. I say X# because other wise you just send armies of 1 unit to attack and run. And it would be a bad idea to make a big army attack with out this.)
Factions that get this are:
Gerudo, Moblins, Lizalfos and Zalo. I'm not sure who else.
4) Hunters and Gathers:
(This is the income gained through the masses Huntering and Gathering in large scale. gain X amount over X time/turns. But can also boost the income gain through some thing similar to how Fair grounds or Lon Lon Racing works. You click on button, some thing happens. I have never used it my self sadly.
)
Factions that get this are:
Kirroki, Deku tribes and Lizalfos. Not sure who else.
5) Racing Tournament:
(Not sure how this would work. Maybe like Lon Lon Racing.)
Not sure who would get this. Maybe many factions.
6) Arena/Colosseum income.
(I guess it would work like Lon Lon Racing event.)
Moblins and Darknuts. Not sure who else.
7) Brothels:
(X chance of getting X amount per X time/turn.)
For Gerudo. Not sure if for Zora.
8) Payed Healing:
(X chance of getting X amount per X time/turn.)
For Zoras and Faireis.
