One thing I think Bay does better than us is languages. Humanity comes from all over space - there's hundred of billions of Human beings. They inhabit hundreds of planets, come from hundreds of ethnic groups. How many languages do they speak? Three. Not counting Tau Ceti Basic, Humanity speaks three languages. Sol Common. Freespeak. Tradeband. In the future, apparently Humanity forgot how to speak every language that wasn't Mandarin, Hindi, or Latin. I know some people will complain about bloat, but I think that language is an exceptional tool when it comes to characterizing people.
Bay has a total of nine languages that Humanity speaks - potentially more, but it's nine at the very least. Gutter is an option too, but isn't available for the character I made. Language changes based on background.
To demonstrate why I think more is better, let me provide a personal example - I have a headcanon Solarian colony that was established by Eastern European settlers. On Aurora, I've had to make up a bullshit regional language - based off of Tradeband. On Bay, I'd have a far more logical option - I'd use Pan-Slavic.
Think about it - why have Elyrans speak Tau Ceti Basic when they could speak Prototype Standard Arabic? Why have everyone in the Coalition speak a single language when the Coalition is supposed to be ultra-diverse?
Ultimately this is something for the lore team, and I know their attention is elsewhere right now, but... Imagine how much more interesting characterization could be on Aurora, if your Dominians and Elyrans and Eridanians spoke their own languages.
EDIT: As a clarification, I am not saying we should have a 1:1 port of Bay's languages. I just think we should have more than what we have right now.
