I don't know if they will go for IX now, given Rebirth's disappointing sales. And I'm saying this as someone who is loving every minute of Rebirth.
Rebirth has lower sales, and it was a given. FF7 should not of been split apart. I never finished ff7 remake, and have other games to play. I won't buy rebirth until i finish remake. I played ff7 in the 90s and have replayed it multiple times. I can wait. I'd rather play dragon dogma2, unicorn overlord, and manor lords, bg3, etc... games I haven't played before first. Especially for a $70 price tag, I can wait for a sale.
People who havent' played remake, won't buy rebirth, people that didn't like remake won't buy rebirth.
Its guaranteed to not sell as well. This should of been forseen as it's not a new game.
The original ff7 was 3 disks, they should of waited and released the whole thing for $70, I think more would of bought it if complete.
As for ff9, meh... its the one ff game I never really played. The kiddie human characters, balloon like monster characters really turned me off. I loved the medieval settings of the original ff games (played them in the 80s - early 90s, but by the time ff9 was out, I had just gotten done ff8 and it was a more mature title. I was 21 at the time and I wasn't digging it. Tried years later and bought the remaster but still haven't played it.
Now remake ff4, ff5, ff6 or ff8 and I am down. As long as its not woktified, or they get rid of turn based battles.
