I still think X-2 is canon though. Sorry. :P
I'm in the disregard Word of God completely and accept the actual work itself, even if I don't like it, camp.
I argue the amount of bullshit you have to do to earn your perfect ending in X-2 somewhat justifies a completely "magical-why-the-fuck-not" ending. So good for you Yuna! You got yer man back.
But it seems like the novel and in-game audio drama allude to the happy couple being unhappy anyways. So uh... ... I don't actually have anything to add, I have no idea what the devs are trying to do at this point with Tidus and Yuna or the series at all. I do agree the most poetic end was the end of X -- that ending was almost perfect.
Word of God or fan reception, I would either way hate to see myself having to work on FF knowing the kind of people I have to please.
Eh. Yes and no. Certainly there is that legacy to live up to when you're hitting on a series' 25th(!!) anniversary; but I think it's safe to say certain decisions writers make that do cause fans to get annoyed can be somewhat justified (I'm speaking broadly obviously, but examples are plenty). The FF8 orphanage story was just kinda weak in general; and throwing in FF9's Necron is a bizarre final boss choice; and of course, FFX-2's somewhat dubious resurrection of Tidus is a peculiar addition (remember how Aerith's death was all meaningful since she stayed dead?), and Bravely Default made a plot point into a ridiculous game decision that arguably tarnished the entire second half of the title.
Yeah there's a big audience to please, a painful part in dealing with growing fame, but I think some plot decisions are arguably better than others.
God rest. I loved him as an actor and I will miss him. :(
