I have not read all of the above ideas, but i think, the first problem is to make the clear difference between the "rare" and "common" events.
Another Question is, what could an event do?
Before i add some event ideas, i will write my "thinkings" about that.
Possible Effects:
- Golden Age (should be very rare)
-

in City for some Rounds (common)
- Add / decrease

/

in a City once (common)
- Add / decrease

/

(very common)
- Add / decrease

to a building or Field permanent (rare)
- Add a standard Unit (common)
- Add Experience to a Unit (common)
- Add Special ability to a Unit (Rare)
- Add a Special unit (Prophet etc) (very Rare)
- Add / loose a Building (rare)
- Add a Non-Race Unit (Wolves, orcs for elves) (rare)
- Add / decrease City population (rare)
- Add / remove Religion from a city (rarre)
- Change Inflation Rate (Rare)
- Add Experience to Race Hero (rare)
- Add Special Ability to race Hero (very rare)
Now some Ideas for "common" events:
- In illness weakens the city (+1 illness for 2 rounds and/or - (city size) food and/or -(city size) production
- The people in the city are happy an love the life (-1

for 2 rounds and/or +(city size)

and/or +(city size)

and/or + 2xcity size

and/or +(city size)
- A soldier is very ambitionated / pathetic (?) and get / loose +2 EP
- The city is good / bad leaded, it gains / loose some

/

- Your Scientists are talking nonsense / genius and will losse / add

- The local gaves concerts and are great / awful so you will gain / loose culture
. Your [Building] has special abilitys and you will gain [food / hammers]
- Insects / Rats stole [city size * number of food storage biuildings] food
- The River is nearly dry, so the people are hungry (- food)
- The River is too strong this time, so some people loose their houses and build ne ones but are ot happy (+1 Unrest for 2 Rounds)
- A Storm damage several buildings during night and much work is lost (- some hammers)
- (on high criminal Rate

Thiefes are in the city and stole many during night
The People are upset, what will you do?
1. Send Guards to search the thieves to arrest them (unit cannot move for 2 rounfs) and give the stlen items back (+1 Luck for 5 rounds, -10 gold, criminality -5)
.2 Send the guards to arrest the thieves and get their stolen things to the state (+50 Gold, -1 unrest for 5 rounds, criminality -5
3. do nothing (+5 Unrest for 5 rounds, +5 criminal rate)
4. Give money to the people, who are victims or the thieves (-100 gold, +2 Lucky for 5 rounds)
5. search the thieves and hire them (+1 unit (whatever is nearest to thieves), +1 unrest for 5 rounds, -10 gold, -1 criminality
6. search every house until the thieves where find and burn all friends and there houses of the thieves and take their goods (-20 crime rate, +500 gold, +5 unrest for 20 rounds, -1 population, requires evil alignment)
General common ideas
- Depending of the position of a city (coast, djungle, forest, river) the production of the ressources cuold change every some rounds (add / remove some points), because natural ressources are not absolute cointrollable.
- Weather is not stable, it influences the income from some ressources every soem rounds...
- some resosurces could spread out (animals and plants), what is a rare but not unimpossible event---
- some ressources grow bigger or smaller and gain bonuses (or negative effects) for axample, a horse ressource is special, some add +1 food, some +1 production, some +1 trade etc. sometimes those "bonuses" change (common event)
These changes can let happen or sometimes improved /hindered.
The [Ressource] improves during working. what will you do?
1. nothing, at the ressource work like ever
2. push the improvment (+1 production, food or something else) (-100 gold)
On degeneration, nothing leads to loss of one point and money could stop the degeneration. Tha could happen very often, because one turn is one year and natural ressources can change. But not all, anials and plkants could be influenced, iron and other could change, but not so often and it should be more expensive.
So my ideas for it
