Stranglehold got blocked? Really? Sometimes I wonder if they pick the games at random so it seems like they are useful or if there is an actual system behind it...
Did it get blocked by BPjM or through some other means?
As Anime-BlackWolf pointed out, strictly legally speaking, it shouldn't have been sold in Germany in the first place. The store page showed the German 18+ rating, but that rating only applies to a cut version that was sold in retail in Germany way back when. The uncensored version, which is sold on gog, is unrated and indexed.
