Had an interesting thought.. though it's probably no more than a thought, i'll share it here too.
Looking at the S5 Dream Date, I also wonder if it's an allegory for player choice too. As in, yeah you can make Cloud choose different paths whether that's who to date or what dialogue option to select, but in the end it doesn't matter because Cloud is only presented with the option that the story/narrative presents, hence why no matter what you pick on this date he's forced by the NPC's themselves to only go with the option they present to him. You can choose to romance one girl in the game, but the reality is that the story is pushing you in another direction kinda deal? Probably nothing just popped into my head
Also regarding AC It wouldn't surprise me if they did something in P3 regarding it.. even if that's just a soft remake of some scenes, or maybe an post AC epilogue at the end.. it'd be nice to see something since I doubt they'd remake the entire film, it would probably feel like a waste of money on their part at this point.
