I didn't read anything but the OP, which I quickly skimmed, so if I say something out of place then excuse me!

I personally don't like FF1-3 because they lack the things I enjoy in an RPG, and have many of the things I don't like. Large dungeons with ridiculously high encounter rates, all of them quite difficult, feels very frustrating and tedious. When I pick up an RPG, or any game really, I want a story that will draw me in. With newer consoles comes the capability to use better quality music and more detailed graphics. This isn't a necessity, but it makes it so much easier to bring a story to life. There's so much more you can do.

Were they good for their time? Definitely. Will you see me playing them now? Well while I have respect for Pong, I'm certainly not going to invest hours of my time playing it.
