Aniplex is not PlayStation, and Aniplex is only the publisher for the game (which is understandable, given that they're mostly an anime and music licensing company first and foremost). However, you will be pleased to know that the Fate franchise has gotten a lot more popular thanks to this game, which explains why there are more Fate games on PS4 now.
Huh? Fate games were revived with the new anime adaptations by ufotable (starting with Fate/Zero, then UBW, and now the Heaven's Feel movies). Grand Order is huge, but Sony hasn't done jack to transition it to PS4 for some really stupid reason.
