Yes, Mugen Souls Z will be edited, but the content that was removed isn’t much. Siliconera asked NIS America to clarify the edits and the bath mini-game that was removed from Mugen Souls will not be in Mugen Souls Z.
A representative from NIS America explained that everything else will be untouched. The story, text, and core gameplay will be the same. Stat increases that players would have received from the bath mini-game will be applied automatically.
Mugen Souls Z is slated for release in North America and Europe next year.
