Natural Doctrine released on April 3rd and it did not chart at Tsutaya Game Ranking chart so I assume it flopped and failed to help sales of PlayStation 4 and its a Japanese tactical strategy turn based role playing gae so WTF Japan... I would at least expect good chunk of PlayStation 4 install base to jump on it since PlayStation 4 lacks games for Japaneseaudience and.this should have eased the dire situation...
