So here's a recent developer interview (miyazaki) regarding dlc and localization for the souls series. Very interesting especially this part
When I was young and reading fantasy novels - and this is at an age
where I could only understand maybe half of what I was reading - there
was an allure to not knowing entirely what was going on. So I had this
idea that perhaps there would be some way to create that kind of feeling
in a game. My method of storytelling comes from that inspiration, from
the shadowy parts of a story or a legend that you can’t make out.
I think they were pretty successful don't you?
