I haven't played any of the FF games at length past 9. I agree with you on VIII, that one was grindy with the draw mechanic, though I liked the story and characters. I liked 9 more as a game, it felt more like 6 than either 7 or 8, though I liked the less cartoony art style in 8 more. I tried one I can't recall the number of on Xbox IIRC when I was living with room mates who had it, but was somewhat disappointed with it, perhaps unfairly, having come from the earlier iterations of front/back line setup instead of the running around in 3d; that one felt like single player Everquest sort of. My favorites in the series are 6, 5, and 7 in that order, with 8 and 9 right behind in unsure order as I liked different things about them. I also liked the Chrono Trigger game, never played the sequel; and oddly enough Mystic Quest was one of my favorites even though it was one of the most barebones; probably because I played a ton of it at a young age because it was one of the rentals available at a local movie rental store.
The console only release is kind of disappointing just as it is for any game that does that, though I probably wouldn't have bought it right off the bat (limited budget, not a hit at it's quality which I haven't assessed).
It's good to hear it might be a quality game.
I've heard some minor complaints about practices by Square in a business rather than creative sense so I left the FF series remakes off my wishlist on Steam when I cleaned that out the last time. They had been sitting there a long time anyhow. Something about C&D orders for using their art assets but then being caught with a Getty images copyright in some of their art in a game, I can't recall specifically.
The series has always had outstanding music, I still love the Veldt song from 6. If you feel like making your own version of the song, I'd guess many of the old songs are available in midi format somewhere. You can open such a midi file in the free trial version of FL Studio (just export the result before closing out the program, as the trial version can't save project files but can export a finished mp3/whatever format) and replace the midi instruments for other instruments, because the notes will remain the same after the midi instrument is replace by a different instrument. That was how I made some music for the LCS game using classical music midis; it was quite easy comparitive to making an original song. Most of the synthesizers have a list of presets to choose from so it's almost accessible to those who haven't the experience to know what knobs and sliders to wiggle around, in that if they can receive direction to that point of picking presets it's a simple swap out of instruments, takes only a few clicks per instrument.
