I know there are FF fans who will get offended by me saying this, but SE will NEVER restore FF to it's former greatness. Sales are starting to slip for the FF games due to lack of interest since FF13 and 14 damaged the brand, Im sure FF15 will only do the same.
So does it matter who the rep is in PlayStation All-Stars? I'd say SE should consider themselves luck if Sony even *wants* FF in PSA
That's not the reason why there won't be an FF rep. Yes the games now suck more than a vacuum but the older games are still really good and people enjoy the characters. Parrapa hadn't had a game in years but he was selected because he's a beloved character.
FF14 has a new director who actually listens to the players and seems to know what a tolerable game is. As long as there's more fresh blood like that when the old, arrogant higher-ups start stepping down and dying, I think FF can be saved.
Pretty much the same way I feel about George Lucas and Rick McCallum dying.
