I posted a hugh list of system names on the Scenario/Mod Archive.
The author says it has over 5000 names, I haven't counted them all, but it is 88 pages long, so I believe him.
The author of the list is Andrés Lescano of Kuat Drive Yards

So full credit goes to him. But he said it would be ok if I posted it here for you guys to enjoy!
Check it out, I think you'll like it.
