Much of the work that the NZ-HIWG (New Zealand branch) has worked its way into FSpace...I am sure that product is also a by product of Traveller groups in Australia, as well. The kanga on the cover sort of gives it away.
Oddly enough this isn't actually true. The HIWGNZ group I pulled together for Meshan was centred around the team writing and playing FED RPG/FSpaceRPG and my AD&D group who helped frame up the world I've spun off into it's own game based on the FSpaceRPG engine.
HIWGNZ existed before I took over and had members not associated with the Meshan project. And several members in NZ contributed to The Meshan Saga with articles who weren't part of the Meshan Sector team.
The Meshan work has several influences dependant on writers. Richard did his own thing, not related to the FSpace work - and he went his own way. Philip was very pure to the setting and rules. My own work got influenced by my own work elsewhere.
I do admit as the genesis for FSpace, it is influenced by my earlier gaming for Traveller (particularly MT with the influence of DGP), but I can also say 2300AD, Palladium's Robotech, Star Frontiers and Space Opera all greatly influenced what FSpace is. At the time I wrote that game I owned not a single piece of gaming material from elsewhere. I sold the lot, then sat down and wrote short stories, story intros and the like before writing some rules and taking things from there.
To do my HIWGNZ work several years later I had to buy some Traveller stuff again and borrow the rest.
Many years later I had acquired a commercial publishing licence from Marc for doing Meshan CT, but during the editorial process of the first book Richard and I decided to go our seperate ways, so that project never got published.
Philip, Aaron and I have been considering what to do with all the writing and art we accumulated for that project.
Although I queried Marc about investigating this again (especially since he got a royalty advance), he was too busy with T5 and hasn't gotten back to me for quite some time.
So if we can't publish for Traveller, we probably are going to repurpose the material and publish either something OGL and/or FSpace so we have clear commercial rights. So in that sense, FSpace could well feed directly off that work.
As for Australians in the FSpace/Meshan group, they are all ex-NZers, even our UK members were all NZ residents at one point. No member of HIWG Australia was ever been involved in FSpace, nor can I recall them pitching into Meshan either. On the other hand NZers had contributed to Australia's Yiklerdanzh project.
Hopefully that provides a little history - especially since I've been vacant from the scene for several years.
