Did you have the basic ideas for each scenario before you started or did you come up with a new one after each game?
For this campaign I tried to write a couple ahead but never more than that. Sometimes outcomes mean I change direction totally in the following scenario.
In others I've written scenario trees to put together a random storyline eg. if this happens then..... if not, then.....
I may also just roll dice foe the next scenario out of a pool of options.
Hope that's of use.
Incidentally, I'm going to play a couple of sci fi games in the coming weeks to see how my Jedi performs, and will stick a bit of a summary on the Future board.
