I am working on expanding the timetable for Galactic Routes (Fly Casual, page 78). I want to add more key systems in the Galaxy, but before I go any further, has this already been done??

There are a couple of websites that have done this sort of thing, but they were never official, and even if they had been they would now be Legends status.

I’m pretty sure they’re linked in the “Compiled Resources List” thread.

That said, if you wanted to do more work in this space, I’m sure that there are plenty of people here who would be happy to make use of your efforts.

I heard the new Force Awakens Beginner Box has a great Map of the Galaxy, which some people feel like it alone (bundled with dice) justifies buying the Box.

I have neither bought nor seen the box in person, but the map included is the first somewhat "official" map of the galaxy since the mouse took over.

Also as other have said, there are several sites dealing with hyperspace travel, but most people on the forum run hyperspacetravel more in an abstract, plotrelated way.
