Re: [nbos] [AS] Multiple Star System Question
Wed Jun 25th, 2008
For me on realism. It depends on what I'm doing. AS doesn't push
suspension of disbelief anymore than most science fiction novels do,
so I see no issues with the orbits calculated as is. I'm also a
consistency fiend. When my players say "Well that's not very
realistic" it's becuase something in my internal consistency is off.
Though they're more likely to assume that anything 'off' is part of a
plot device. But even a fantasy world has rules of what is and isn't
possible... and has perceptions of what is and isn't possible. And
it's the difference between the two that frequently allows you to
surprise your players.
