It offers no open world mode, would be impossible to convert to mobile and is extremely difficult to play at a competitive level. (invenglobal.com)
Apart from the story mode, there are also Free mode, which enables players to revisit any battle previously completed in story mode, as well as Chronicle mode, where one creates his own character and journey along Japan, creating a sort of history of that era by engaging in missions, small or large, across a sort of an open world mode where one may run across a map of Japan with a huge version of your created character.
