This is an interesting discussion. Many people coming up with excuses.It's fun... let's join.
Before Remake released, I mentioned how the success of this series was going to be determined by the sequels success. This came from when discussion about it being split up came up people kept talking about FF13 and how it was a 3 part series, I mean it wasn't stop trying to compare. 13-2 sold decently compared to 13 but 13-3 was pretty much a 3rd of both of them. If it is a series then well, 60% of all FF13 players never played the end of the story. Of course it's not because FF13 was a self contained game with 2 sequels.
FF7R though, is exactly that, a multipart series. We know the full game already from 25 years ago and even if many are waiting for a 'full' release, that won't help in between and waiting potentially a decade for it to arrive. SquEnix resources have been put into this game as they claim they need to "do it justice" but how does that help appeal to people when the market for this particular FF game is so small? You have to have played FF7R, liked FF7R, maybe like FF7 and FF in general to pick it up. You think people are going to pick this up as their first FF game? Doubtful.
But even here it's hard to compare sales. FF7R sold what 7 mil? Yet it was given to PS+ users at one point, it's how I played it. 7 mil plus untold amount of PS+ subs and it still can't compare?
They were better spent their time developing and producing the technology to make FF7R, make the entirity of it 1 game, butcher the gameplay all they like but then move on to new FF games.
We are now at the point of having FF 16 and FF7R-2 released and no announcement for either FF17 or if R-2 fails too much, even getting a R-3 to finish the story for those who actually liked it.
Sad times.... of course, all i can think is "Good, should have just made FF7 like they said they were going to."
Hmm, pie.
