Exactly. I haven't paid any attention to the game, but just took the throwaway references to offscreen stuff to be the usual random bits of jargon you run across in scifi universes.
Take the original STAR WARS, for instance. None of us knew what the "Kessel Run" was, or could look up the infamous "spice mines" on the internet. Heck, we didn't even know what a "Hutt" was (as in "Jabba the Hutt"). We just accepted that that the writers were trying to convey the sense of a larger universe and that it didn't really matter if we didn't know what exactly the "Clone Wars" were . . . .
It's like when STAR TREK does the trick of invoking "Galileo, Einstein, and Curcovissox." You're not actually missing
anything if you don't know who "Curcovissox" is. You just go along with it . . ..
The only difference here is that maybe Curcovissox showed up in the computer game at some point, but you don't really need to know that to enjoy the show. I'm sure that if the TV audience ever needs
to know who Curcovissox is, the TV show will be sure to provide us with that info.
