I made a game about a village in northern Germany year 1
I have a great love for mythology (from various regions, though specifically norse mythology) and have wanted to use it as the background for a story.
I finally dared to do this two years ago.
I did NOT anticipate how hard it would be to research for this.
I have various editions of the edda and kings' sagas at home both in German and English (and every time I was looking for a specific song / text it would be one missing from mine :D )
I also relied HEAVILY on the work of Rudolf Simek whole "dictionary" was invaluable especially since he is very open about how vague some of our knowledge is.
