It's still very popular in Germany with new adventures, boxes and also a lot of novels set in the universe being released.
As an aside: I also really like the old PC games "Das Schwarze Auge: Die Nordland-Trilogie" (Realms of Arkania in English iirc) but it's a very unique/strange adaptation. It's very close to the game system but has been criticized quite a bit for the gameplay content (I actually liked the storylines). When you selected the complex rule system it was very fun to just level the characters and try all the spells etc.
The round based combat was also very unique/interesting (imo)
