I will freely admit that I am something of a young 'un here (1st edition came out when my dad was in College and my mom was still in high school), but I did discover the PDFs on Wargames Vault and am contemplating starting a solo game of Starfire III: Empires.
The problem I'm finding (aside from needing to get counters and a map, which I have solutions to) is the absence of the System Map for Starfire III. I did fortunately find a review which included the maps and it does look as if my stopgap solution of using a Traveller sub-sector map with the occasional world pencilled in should work and arguably be infinitely expandable. Still, I'd like to get some input on what the more experienced Star Lords would do for not only Empires, but New Empires as well.
