I've tried to find a more descriptive subject header, but I'm at a loss.. basically, is Aurora-space a "tree" or a "web"?
I've finally got a game which has lasted over a decade without either mineral or economic collapse (knock wood), and so I've got about 20-odd wormholes charted, and I've noticed, so far, that once you're along a route, it never connects to stars on other routes. What I mean is..
Say your home system has two warp points, A and B.
A leads to A1, A2, and A3
A1 leads to C1 and C2
B leaves to B1, B2, B3, and B4.
B1 leads to D1, D2... D5.
I have never seen a gate that leads from C1 to D2, or from B4 to A3, or from B to D5.
This has some interesting effects. If there are aliens sitting on the other side of a home system warp point, there's no way to "sneak up" on them, no matter how much of the galaxy you explore... all of the worlds beyond that gate are blocked off until you kill them.
Unless I've just been unlucky and there are such "cross-branch" links.
