That's a pretty awesome map, thanks for sharing!
I agree with the intensity of seeing the demise of the RWR collapse, but what I found equally remarkable was the big interior colonisation of the Lyran Commonwealth during the age of the Star League. I think I never though about it. Although by comparing maps dating from the foundation of the Star League and its end or the early Succession Wars Era, it becomes clear that the information was out there.
But I never read about it. To me, it looks like the LC gained at least two thirds of its systems during that period, perfectly peaceful and without conquest.
