Ideally we want to do as few updates to translated strings as possible, to not trigger re-translation in all languages.

I'm fine with this. These grammar errors are not present in the translations so a simple save & review does the job.

My belief is we're generally following British English.

I don't think (as an American English speaker) that there's anything necessarily set in stone regarding use of one or the other, but the existing precedent in our language strings is for the British spelling rather than the American spelling.

That being said, thanks for the spelling fixes! It's definitely worth a bit of translation workload to address mis-spelled words, especially when we have (at least) several weeks for the translation churn to be looked at before a release.

It's because it was started by TomM (UK), I'm UK, RobN (AUS), plus a few others... also given my other career it's been nice to work on a game where we could keep the UK spellings 😆

Heck, I have a whole crapload of such fixes if you want 'em, as well rewriting headlines as headlines (i.e. not as prose), having taxi passengers say different things depending on their occupation, and so on. Takes me ages to re-insert my fixes into the game every time I update it...

I'm happy to translate more strings.

Here are my current language files. http://www.keeper1st.com/pioneer/data.zip Not all have had corrections or changes, but most. Some are minor punctuation like fixing improper comma usage. Some are actual spelling issues or cleaning up awkward prose (e.g. "No more space for more cargo"). Some are more important like not assuming the player is male. Some are rewrites (e.g. taxi passengers either for more variety in what they say or in making the way they talk reflect their profession). Headlines are rewritten as headlines and not prose (e.g. instead of "The gas algae harvest in the {system} system is above average" it becomes "Gas algae harvest in {system} above average"). One is a little nod to modern air traffic control: adding "Good day" to one of the sign-offs from a station as you leave their space.
