Brother, Darklands is like top 5 RPG settings. You could hardly have chosen a worse example.
And what, exactly, is the setting of Darklands. Isnt it something something medieval, something something european, most likely, germanic , like Holy Roman Empire.
What, exactly, is unique or much invested in the setting of Darklands? That is not coming from historical source, I mean.
The one weakness of Darklands is actually its setting, Holy Roman Empire. I mean, I love that period, kinda like Romance of Three Kingdom but european instead of chinese. But as a storyfag I can tell you straight out that it's niche as fuck. Nobody other than some indepth, esoteric-loving, storyfags would play games in that setting. I mean, the earlier Roman Republic/Empire era at least there's some characters you can name like Caesar, Pompedue, Cleopatra, some stories you can tell, like Caesar rise and fall to power, etc...
What, exactly, is characters and events in Holy Roman Empire you can name? The owner of courier service, Tarick or Thur or something, nobody remember or care. Event? nothing~ There is, but, well, nobody care outside of HRE-major historical students. I think there's a golem origin story, but I think that's Jewish, so it's not Roman, not Empire, and certainly not Holy.
The main reason that, despite its strength in gameplay, nobody would play Darklands much or mention it... guess what? yeah, its background setting, Holy. Roman. Empire~
