I had english lessons since I was 7 and went on with secondary school 8 lessons /week, then took part in international youth trainings from participant to supervisor - communication only in english...Trust me
American english is just lazy and wanted as much simplicity as possible. It is not a black-or-white good or bad thing. This is a big advantage to become widely "spoken" language. Brittish english - what a surprise - is much more locked on traditions, and so keeping on formalities even if it makes challenging to use. So "optimal" for RimWorld would be between the two: diverse words to have one meaning by one word, but simple enough to stay simple and straightforward
So Autumn would fit, no matter if it is canonized brittish word or a trend from any decade of american history.
