Haha good point. However when Ps3's user base was at like 7 or 8 million in 2009 and PS4 is at I think 1.1 million in Japan, there is a big difference that has to be addresse. it looks like that almost half the people who had the Ps4 bought the game.
No, actually that's wrong. The PS3 userbase just before FFXIII came out was like 4 million. The PS4 userbase just before FFXV came out was 3.6 million. The hardware gap isn't that wide. People are just sick of paying 8800yen for garbage games when they can play awesome free games on their phones like Terra Battle from the Father of Final Fantasy instead.
