As a GM, part of the fun of writing an aventure or campaign background is coming up with the little details like names of things, what things are made of, which companies manufacture them, on what side of the hills is the best growing conditions for grapes versus apples, and so on.
Just be aware that you're doing all of this entirely for your own personal satisfaction.
[Reminder: Our guest commentators have not seen Rogue One. Part of the fun is seeing how their untainted impressions re-interpret the movie through the lens of our comic.]
Bow-Tie fighters? What kind of name is "SFSL fighters"?
Note that all four players are in on this.
"Jim, he has asked you not to alter the name any further. So no 'pie' fighters, okay? I pray you don't alter them any further in the final trilogy."
I like how the GM is actually come up with such names as "Ls-1", or "Quadanium steel solar" (presumably panels). Such detail, completely ignored by the players.
Except you can bet they will be wondering where the "Ls-2" guns are later when they are in the weapons facility.
Ah, so the PIE fighters were once TIE fighters. This explains... absolutely nothing.
On the plus side, I bet those models do look really cool, and they'll look even cooler once Sally and Pete have retrofitted them to spin around and squirt water.
GM: Imperial fighters launch to defend the facility. I've got some cool new models for these.
GM: They're Sienar Fleet Systems Line Fighters.
K-2SO: They look like bow ties.
Bria: Cool! Tie fighters!
GM: They're not bow ties... These wings are quadanium steel solar—
K-2SO: Solar powered bow ties? Do they spin around?
[SFX]: Pow! Pow!
GM: Well... yes, but—
Chirrut: Do they squirt water?
GM: One fires an Ls-1 laser cannon and blows up a Rebel fighter.
[SFX]: Pow! Pow!
Chirrut: Impressive for a tie fighter.
GM: They're not—
Cassian: How many of these tie fighters are there?
GM: Okay, fine, they're TIE fighters. Just don't change the name again!
