I've changed it for you.

I’m evidently less familiar with XenForo than I realised when registering, because I didn’t realise that the display name was what other forums refer to as a username (for it's unmodifiable, by me): If that’s accurate, I want to replace it with “Roke Julian Lockhart Beedell”, instead. Can I?

Thanks to @stevenlauthere is now some footage of me getting my @#$% kicked by him   Classical Warfare AEA youtube channel!

I’m bringing more news about the World Rising project! All natural resources have now been created and fully implemented into the game! In addition, the first map has been completed and finalized! Check out some images of the new natural resources that will be part of the game world! The next step will be bringing the new animals to life through animations, as well as creating the second Japan-themed map — there will be 3 Japanese-themed maps in total. The project keeps moving forward step by step, always focused on quality, immersion, visual authenticity, and optimization. More updates coming soon!

No. The other way around, as you are correctly describing in the paragraph below. Your traders don't buy or sell anything; they walk their route and when they make it to either end, they get you an income of the specified res. If you don't manually buy or sell metal there is no "exchange".
