I'm not sure what all events are on the alpha server (yet) but if you're game I'm thinking a procedurally generated event system could start filling some of space's void. Any of these ideas sound fun?
I already have a mini script for the main story/quest line.
And for the side quests/events. I have over 50 ideas for now, they just need to be created as events xml files.
I suggest you look into the example.xml2 file in the Server\WorldGen\Events folder.
And see what you can do with it.
I haven't added a model.xml file for a0.6 version yet. But you can check out the model.xml_ file in the a051 version of the game.
Though it doesn't have all the new features and the format of the event files has changed in a0.6, still you can find some explanations there.
(I will make the model.xml for a06 version a bit later)
