Possibly also remove “A long time ago…”
Absolutely not.
Every piece of Star Wars media — the video games, the novels, the comics, you name it — has had “A long time ago, in a galaxy far, far away…”
The fact that Rogue One didn’t have an opening crawl was an insult enough, but I got over it. Getting rid of “A long time ago” would be an insult to the franchise.
