The fact that the board's non-route distances ARE NOT congruent.
... is, as I said, an unavoidable artifact of projecting a 3D space onto a 2D surface. The differences stem from choosing a slightly different projection, not from a different underlying reality.
So, Chris, they are not representing the same space well, even if the names are mostly the same.
No, your examples are flawed (though the fact that you're even able to make the comparison should tell you something).
A jump-2 ship (which is all that is available during the period
Imperium represents) travels the
Imperium board in
precisely the same manner and by the same routes that a jump-2 ship travels the Solomani Rim map. If it quacks like a duck...
The "non-jump" distances are irrelevant: it is mathematically
impossible to represent them consistently in both magnitude and orientation on a 2D surface. In any case, non-jump crossings are a tiny fraction of the total in both games: a marginal but sometimes useful stunt, not fundamental to either one.
Looking at the higher-than-J2 links, it breaks. Even then Imperium uses ONLY j2 links, making no distinction about lesser drives.
Actually, you pointed out yourself (above) that the links are "jump-2 or less"; there are a few jump-1 links included. "Lesser drives" are effectively useless, anyway: the average distance between star systems is much greater than one parsec.
The same mathematical limitations I mentioned for non-jump-distances apply to jump capacities greater than jump-2: if it were possible to depict them consistently in 2D, they simply couldn't be taken from a 3D original. Jump-3 or greater connections on the Solomani Rim map are "broken" with respect to real world distances, too, because there are far too many connections to represent consistently in 2D. The jump-2 projection works because it's a single scale, because it's just under the average separation between systems (i.e., few connections), and only because of the limited area involved.
"Accounting for the difference in scale" as you originally allowed, how do you expect the two maps to be any more similar?
