"If SD wants to please everyone, have a box to turn mega events off like in GC2."
Have two bars. One for severity, another for frequency.
Minor:
Have food production in one town cut in half, or doubled.
Minor increase / decrease in gold or other resources.
Major:
Training of one troop in one town completed instantly.
Food production in empire goes up, or down.
If there are mines outside of town, have them run dry for several turns producing only half as much, or twice as much.
Extreme:
Complete a research project in half as much time, or twice as long.
All troops currently being trained are finished.
Plague hits a town causing half its population to die.
Or people fleaing a catastrophe flood a city causing its population to double.
One town hit by earthquake losing some population, some troops, and some buldings.
MEGA!:
City goes bye-bye (asteroid) and 90% of all people, buildings, and troops are killed.
Neutral city joins your ranks.
All buldings currently being built are done, or have to start from scratch.
Maybe even have checkbozes for types of types of events.
Maybe you only want resources changed. Maybe troops volenteering (or deserting). Buildings being created or destroyed populations going up or down. Magic spells. Items for heros. (Imagine learning one of your magic items was a fake, and the temporary enchantment just wore off.)
Options!
I want options!
(On a side note, this is why I'm really looking forward to the Beta Tests.)
