It kind of bugs me that you guys are just calling it "not being able to recreate nostalgia". While the game had certain flaws that needed to be overlooked and that I would like to see corrected, the things that make it special isn't the childhood memories, but the fact that the spirit of the game and what it did well was really good and holds up, period, in any context. If they preserve that and make a game that nails that quality (whether by keeping it or improving it) and improving the finer quality of life details, that's all that matters to me (and that's what I doubt will be successful). Who cares about nostalgia/sentimentality and who cares about keeping things fresh and unexpected. Those are superficial novelties that have little value or substance, IMO. If something's legitimately good, it's good even if you're aware of the beats ahead of time.
I would hate for them to make random changes for the sake of the temporary shock value of being unexpected/"fresh" for long-time fans. If anything, THAT'S the kind of creative decision that becomes dated quick.
Just do whatever works best.
VII to IX are serviceable (I think they're just the PC ports, right?-- Assuming that's the case, VII is buggy and IX might even be an upgrade), but the earlier ones are abominations that look infinitely worse than the originals, IMO. The up-res-ing just looks gross and really poorly done. I cringe whenever I hear about people being introduced to the games through them.
