This is very true of c64 games, which had the powerful SID music chip. I didn't realize until I was an adult how much of the emotional draw of those games was tied to music.
I am very sad never to have had a C64 at the time pretty much because of the SID. The first (and for a while only) computer/console I had was an AtariST which had decent sound chip too but looking back at what people are, and were fondest of, I feel I'm missing out on the nostalgia a bit.
However, I did get Bitmap Brother's Magic Pockets... and now the intro music is stuck in my head... Betty Boo.
On a tangential note, does anyone remember many games that had their soundtrack on audio cassette? I had a copy of Star Glider 2, which had a synth-y track on tape, which you were meant to play on your hifi while playing the game.
Carrier Command was one of my favourite games, but I don't recall ever having a tape soundtrack. Looks like I was missing out.
I tried playing it again recently though and, although there was the nostalgia there, but it just wasn't the same. As someone else mentioned, some games just haven't aged well unfortunately.
