I'm working on a lot of the logic for stories at the moment (making sure the game reacts properly to any decision (or indecision) the player makes. To help me get my head around the stories more easily, I sometimes flow chart them, and I thought you might enjoy it if I posted one such chart here.
This is for a story called The Haunted Station by C B Johnson. The flow chart kinda gives away what the player does in the story, but no details. So check it out only if you don't mind that sort of thing.
The game has over 100 stories like this one, varying wildly in size, purpose and tone. But this should give you a bit of an idea of what an Objects in Space story might entail.
