A while back there was a conversation on this subject, and something caught my attention:
I'm curious, where in Gurps is this at. I was also wondering if anyone had done work on jump shadows with the new map data for the Spinward Marches.
Jump shadows, and jump masking.
Different systems seem to treat it differently.
In Gurps, it's canon, they're really clear on that. They have tables to adjust the travel times based on whether the planet is on the wrong side of the star, etc.
The other versions don't talk about it much outside of simply the 100D rule.
And then there's the whole "shouldn't it be some tidal effect based on mass of the entity", but that's a different kettle of fish.
