> It doesn't get the attention that it deserves as a module and setting. Weimar Berlin is practically mythos-tastic in and of itself.

I suspect weimar berlin is just pretty difficult setting to utilize; in particular you would be trying to draw inspiration from and evoke art/media of the time, which in this case would be stuff like German expressionist cinema and modernist literature which do not have exactly mass-market appral, compared to e.g. victorian era works.
