This version of Yggdra Union is a likely an alternate release or a different regional version of the game compared to the other entries. Lacking the subtitle "We'll Never Fight Alone" suggests it may have had regional changes in content or distribution. The 'Independent' designation hints at a possible non-mainstream or self-published release.  Details on specific differences in gameplay, content, or story compared to other editions would require further investigation.  Considering the success of the other releases, this version might hold regional interest or minor variations.
