Having done some prep for the forthcoming Star Trek game it's reminded me of how unwieldy its canon can be. Whilst I am more a fan of the episodic original series, the Trek canon has built up in layers over the years of course but it hasn't been immune to the whims of corporate forces. As we are generating back stories for our characters it's quite easy to go down rabbit holes and pick up loose ends as so much of the Trek context is just dropped randomly into various bits of dialogue across the seasons - it's not particularly a complaint but it has been difficult to reference even some well known entities as much has been incidental and also inferred.
To be fair it's a breeding ground for the imagination and not necessarily a bad thing but unlike Lord of the Rings or Dune for example, the detailing for Star Trek has not been s singular vision. This is why in part I am an original series fan. It's not so much that they were consistently focused on major issues on a purely philosophical level and arc agnostic but because Rodenberry was alive to own it all. Naturally as it's been franchised out over time, it's become a victim of its own successes and failures but I cant help feeling that Warhammer has kept more of its integrity than Trek but perhaps that's because it's purely prose rather then having to follow the Hollywood fashions.
Nevertheless I still watch it all and whilst there is always a feeling that although it has been done to death after hundreds and hundreds of episodes role players can have a special place as curators here as we can keep the vision intact and hand down our own stories that help sew the universe together.
