I have run the same weekly TNE campaign since 1994 (with the same group and only 1 character has died). In my campaign the players founded "the Library" an organization whose goal was to bootstrap all RC worlds with enough knowledge to put them first at TL 11, then 12 and now in the year of 1209 TL 13.
The "Library" is also a underground Psionic reseach base, though no institute but only the players and three NPCs know that.
So because their fascination with Psionics I have expaneded and altered the psionic powers from the TNE book which I think were a bit few and boring and the players know of registered psionic powers (from the first imperium and forward) and have seen theories and rumours of another 10-20.
Also, I grew tired of mr Maggart and had his shuttle dissapear in mid jump, leaving open for conspiracy theories and accusations. He was too perfect, too goody-to-shoes.
And the Hivers have been the bad guys, the players found a world that had been popualted by humans once, and after some research they discovered that the Hivers understood that they could not manipulate humans that easy and nuked the world. This news managed to come out to the Coalition and to the Ithklur who began a conflict back in the federation...so Hivers are no more in RC space.
I repaced those with the sandman virus, as well as uplifted dolphins, the droynes from Tiyanyd and some ithklur who have sught membership as fugatives from the conflict in the hive federation.
But humans are the major people in the RC.
It seems to be the way that the players want it

And if they are happy - so am I
