Does playing the original spoil the new version? Like, will I be able to run it with players who have already played the original?
I'm going to include a section that covers what to do scenarios for tables that have already played the original and had things go... sideways on the station.
So, yes, you can run the content of the book even if you've already played the original. Though it will require a little tweaking depending on what the results of the initial adventure were.
