This seems much less like a conscious artistic decision and much more like a filler greeting that's been used back in the day and never been changed. I don't see any logical reason why the whole buccaneer brotherhood and their danish ambassador friend would all be patriotic shipbuilders from the Netherlands.I might be willing to change it up, but we must also respect the previous Modder's work, i think there was a discussion about this recently started by @Fluen...
I followed that discussion, and I understand that there are areas where changes would disrespect previous Modder's work. But in general, I think we shouldn't be too afraid of making changes, clearly not when they're improvements. It's not changing the story, it's removing a case of almost every one of many characters using the same, weirdly out of place voice clips.
I looked in the alias file and I first thought I found a lot of duplicates that could be removed to save space, but then I discovered those must be the ones that @Grey Roger already did comment out to save space.
At which point should I do Justine Le Moigne and the other customised sidequests again?
