the computer running us all as a simulation is low on entropy in its random number generator.
(i wouldn't count this as spoilers, it's the premise of the story and none of it is kept as a secret from the characters, but your definition of spoilers may vary)
Dungeon Crawler Carl is sci-fi, because the dungeon where all the fantasy-style magic takes place is like a huge Star Trek holodeck, with some privileged players having safety protocols turned on. Carl can't cast any magic when he's outside, like back on the surface. Changes to the player's body, like Carl's increased strength, seem to be real effects caused by real genetic and matter manipulation, but other people who've gone through body changes that only work in a fantasy setting start to worry that they now can never leave the dungeon, or they'll die if the computer running the dungeon environment crashes. Galactic politics between various alien species becomes more and more important to the story in later books.
the actual Genesis explosion at the end of the movie was a practical effect.
the CGI part earlier was presented as a CGI simulation they watched on a screen.
it only ever went briefly right - it took a ludicrous amount of takes, up there with the Tobey Maguire tray-catch take.

the first words on screen are "a long time ago, in a galaxy far, far away"
so it's definitely set in the distant past.
people in the Star Wars galaxy don't know which planet humans are native to, so while they may be native to that galaxy, there's equally little evidence against a time-travel event, and humans there are Earth humans from our future who went tens of thousands of years back in time as well as moving to a far away galaxy. This could also help explain why humans there use Latin and Greek letters so much.
being ginger draws unwanted attention to him being James Hewitt's son, not King Charles' son.

PieFed did some policy change on... weighting votes for people who vote thousands of times a day, or something like that? PJ said that made him want to change instance again, but he'd done that a few times already and couldn't be bothered with the process again. (this is from memory, i haven't double checked while writing)
even so, the connection was confirmed by Shelby on the ground in Best of Both Worlds Part 1 - she and Data scanned the scooped-out area and matched the method to the lost border colonies.
a more direct Scotty connection to "bucket of bolts" is the end of The Voyage Home - Sulu says he hopes the crew are posted to Excelsior and Scott incredulously dismisses it, his former posting, as a bucket of bolts.
also, we've seen humans on Vulcan in Amok Time, The Search For Spock, probably some Discovery, and none of them had any apparent difficulties with high gravity, Kirk could even fight, and you can bet Bones would have grumbled about it.
I would say it's The Voyage Home that established warp 10 as the ultimate threshold, a few years before TNG.

showrunners said they would like to, but it's not happening.
there was a brief TAS style animated ad for the resort planet in episode s04e03.
