I have noticed some new Youtube Let's Play videos of Simutrans with a German commentary, here (https://www.youtube.com/playlist?list=PLvnGI09NWWNCb86yuWbI4MANZ8e9OseLE) if anyone is interested.
That one went to the German forums and asked for permission/clarification on whether he could use Simutrans in videos, just a bit after they were already published. Seems no new content came out since that was brought up.
