I feel like short of making it free to play and having a complete art style rework this game doesn't have great hopes of ever being relevant. I mean from what I've gathered the gameplay itself is decent to good. But yeah they just misfired so hard with this.
Despite it all, I feel bad for the majority of devs who spent so much of their life working on this and who are likely going to be out of a job. Of course I don't know anything about the inner workings, but I'd be willing to bet it's not most of their fault's that sony had been pushing so hard for live service stuff under their former leadership
