Hello, all

I think perhaps there are so few YouTube “advertising” OA because people who might create them are instead having too much fun arguing about discussing the setting.

Also, there are quite a few 3D descriptions (with some limited interactivity to change the viewpoint) of planetary systems in the setting, developed using Celestia. They can be more fun than just watching passively. A scripted tour through them might be desirable at some point, perhaps.   See https://www.orionsarm.com/page/326

Yes, I've seen some of those, very interesting looking stuff. They definitely have a unique look to them.
