You don't NEED a remake, that's the thing. Play the original. Let Square Enix focus on making new Final Fantasy titles so that they can become classics the same way games like Final Fantasy VII became classics. I'm sure most people will forget all about the original when the remake would only improve upon so many things, if not just the graphics and cutscenes.
Furthermore, the expectations for remakes are way too high. Afterall, you're ONLY asking for a remake to the best title in the franchise, right? With that said, you can't say die-hard fans expect anything less than perfection. And it's funny that I bring this up because I remember a couple members saying that Square Enix's products have decreased in quality, so you expect a remake to be any different? Lol, I'm just saying... :/
I mean, if you're asking for a remake, you're not appreciating the original. The "best Final Fantasy" is a classic that no remake can do justice because it's already perfect, despite how outdated its visuals are today.
