I read that Nobuo Uematsu was influenced by Beethoven and other classical greats. He actually writes his pieces with similar structure -- there is design, order, rationality in his various works.
He was able to create pure coherent melodies, the kinds of melodies you instantly recognize as good (as opposed to "develop a taste for"), things you can sing, whistle or hum by yourself. You don't get that nowadays with modern movies, video games, etc. -- the technology is too advanced.
But in the 8-bit and 16-bit era of video games, all you had was synthesized music. So all you had was melody and harmony! And this composer stands out head and shoulders above all the rest who tried their hand at composing melodies for these music chips.
It's an example of how some of the best creative works come about when the means are LIMITED. It gives some structure to the creativity. When you can do literally anything, creativity is much more difficult.
