smiths 121. There should be NO Border Worlds before the 5th Frontier War! " ...the establishment in 1111 of the Border Worlds Confederation. The new polity was organised as an Imperial client state consisting of (Beater, Biter, Bronze, Durendal, Dyrnwyn, Hoffud, Iron, Mithril, Steel, Sting and Sacnoth..." Page 21 GURPs Sword Worlds). Starports in GURPS are rated 1 through 5 in Roman numeral corresponding to E to A in old Traveller money. This is actually a conversion over to GURPs Space which was part inspired by Traveller. So any such reference in Mongoose Sword Worlds to such is clearly lifted from the GURPs source.
Are Drye, Rancke-Madsen (A keen SJG forum presence still I think) and Prior, the GURPS Sword Worlds, authors credited? Maybe they were consulted or Marc Miller gave some kind of special approval. This would actually have been a sensible move to make up front as their work is excellent and could have given a useful cultural basis for a campaign/scenario pack). It seems to seriously mess up the Sword Worlds region for the 5th Frontier War though (assuming it happens in Mongoose Traveller...). I know Mongoose have borrowed creatively in the past. My Lankhmar Unleashed city maps are all lifted from the TSR D&D release (And aremuch poorer quality than the originals...). I assume Mongoose had the right to do this, so maybe they had something similar going on with Steve Jackson Games/Marc Miller?
