No version of Natural Doctrine charting on Amazon JP top 100 atm. Lots of people complaining about the difficulty, and there are some complainants about the graphics of the PS4 version too.
amazon review said:
It does not have advanced only to the middle, but is evaluated as follows. 1 graphic PS2 average. It became the lessons that should not be expecting a beautiful graphics just because PS4. 2 The length of combat time. It is a game to advance to think, but 70% of the time combat is turn the enemy. Skip, simple display not more I like the game of difficulty difficult. 3, wanton death is often. 　You can only go remember dead as Dark Souls, but please think it's gate to death the boss to take a few tens of minutes determined. 　Things that went carried out very carefully for a long time, become repeat vain Some tough mentally.
