If PS4 was backwards compatible, you'd probably even be right. But I don't think many people play on PS3 anymore, or still have it hooked up.You just wait, after people get their hands on this they will rush to the PSN store and buy Yakuza 0 by the millions next year making Sony swim in cash.
PSN store being wonky now.
I managed to "purchase" the free Yakuza 5, yet now it still shows up as "Free", not "Purchased" on the web store. When I try to add it to my basket, it says "You are not eligible to purchase or download this content".
It's still in my purchase history but NOT in my Download List on the web store.
But something can be changed because it's not only free, it's on this month PS+ free games section.
This bothers me because the series deserves your money.
Really hope you people come through for Yakuza 0
