I had a lot of opportunities to play this game over the years, but I passed them up, having never played a Metroid game or a first-person shooter (hey, I'm a Nintendo guy). So I finally got around to playing it and... great! A little tough in some places, but it's otherwise a classic in my book. I just can't muster the same enthusiasm for the 2-D Metroids, though... Guess that's what I get for playing MP first.
