Yeah, this is not a new concept and I remember seeing one of his videos that explains this concept really well. Here the relevant video from 9 years ago for those uninitiated:
As a native USA, english speaker, I come across this usage enough that it was familiar and not out of place.
The second noun definition[1] and first verb definition[2], but only after expansion, google gave me[3] match.
The second verb definition[4] on merriam-webster.com, similar on dictionary.com, second noun definition on cambridge.org, but mostly missing, in an example but not definition for some reason, in the verb section.
[1] the point from which an activity or process is directed, or on which it is focused.
"the city was a center of discontent"
[2]occur mainly in or around (a specified place).
"the mercantile association was centered in northern Germany"
have or cause to have (a specified concern or theme).
"the case centers around the couple's adopted children"
"Centers on..," would be pretty normal usage. Making it active, like in the article ("Centers at least one...") is a little bit unusual and I can't recall seeing that usage before. Swapping it for 'features' would of course be completely unremarkable. It makes sense though, I don't mind it.
You should try the Brave New World mod for FF6, if you ever feel like revisiting it. Vast QoL improvements, among many other welcome and interesting changes.
I used to following a twitter account that would post the average CO2 level each day, and I distinctly remember the few weeks where I started to see a few 400s amongst the high 300s, and then, finally, never saw 300s again.
