Welcome and thanks for joining the forums! Appreciate the suggestions for music, we have already chosen a composer, you can learn more here: /viking-composer-dean-valentine-joins-rune-ragnarok/ These music suggestions would be cool for community-made videos at some point 🙂
Pardon me, but I think metal genre doesn`t entirely fit for games like this. IMO metal soundtrack suits better for the dynamic parts of gameplay like it was designed in games like Serious Sam, Painkiller or DOOM (2016) – mix of ambient, orchestral and industrial rock.
The right choice for Rune could be something like martial industrial or folkish ambient. I’ll share a sample that kinda describes my point.
This is Norwegian musician dubbed Mortiis who described his early music (1993-1999) as ‘dungeon synth’. It sounds quite simplistic and sometimes boring by the modern standards of production, but this may sound just fine for old DnD or Heretic/Hexen games.
