Milestone of 7 million copies after many years of waiting

The news about Sea of Sorrow comes just as Silksong reaches an impressive milestone: over 7 million copies have been sold, not including the massive number of players experiencing it for free via Xbox Game Pass. This is an impressive number for an indie game, especially considering Silksong went through years of delays before its official release, one of the most closely watched game development stories in the global gaming community.
