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.
Don't worry, I'm sure that PS isn't going to pass this opportunity by...is what I would've said before looking into this further. But hey, Grand Order got an arcade version, so they can port that money printer over to PS4 and call it a day.
I WON A BET AGAINST AZUREN! WOOOOOOOOOOAAAAAAAAHHHHHHHHHHHHHHHHHHH
