I used to make events for Galactic Civilizations II and Civilization  . I'd like to add a few more; I can't count the number of times I've backed that damn young Upstart!

Any recommendations on where to look? 

Hey EccentricOwl!

"Vanilla" random events are defined in ES2 Game folder/Public/Quests/QuestDefinitions[RandomEvents].xml.

You can look at how they are constructed, and use them as a base for your own events.

Additionally, we released a quest mod example here: http://steamcommunity.com/sharedfiles/filedetails/?id=937861604

lilyophelia also recently released a mod which adds a long storyline which uses the Event system ! http://steamcommunity.com/sharedfiles/filedetails/?id=1221844082

Quest structures are slightly complicated (especially if you want the player to actually have to do things), so don't hesitate to ask if you have a question, both here and on the Amplitude Community Discord!
