It is cute that they made an abstract virtual version of the festival terrain and that you can see fans on their cams in the crowd.
Sound and overall stream is great, so that's nice.
I think the social media accounts of Wacken really failed to promote this well btw, in the sense that only just now it became clear to me what their approach actually is. Shouldn't have been that hard to communicate. Maybe it was different for Germans, as this "worldwide" edition still has a lot of German language in it.
On a sidenote, Wacken probably has one of the most extensive and well produced backlogs of metal concerts out there. Nice to see they put it to use.
