Wasn't it Frank Klepacki that composed the music for Dune 2.
Stephane Picq worked with Cryo interactive for the first Dune game.

Dune II, the one demaked here, had its music composed by the inimitable Frank Klepacki: https://www.frankklepacki.com/ost/vg/dune-2
Stephane's work is a combination of masterful composition (complex melodies, progressions, not the typical three-notes of the time), engineering (as the tracks are limited in number in the MOD files) and also synthesis (as most of the sounds he produced himself on various hardware). Of course we could expect more from the mastering perspective, but I doubt this OST ever reached mastering level, and besides - most if not all of the eurotrance that got released in the 90s is subpar to these compositions if you play them side-by-side.
The only times people got close to such engineering feat with early PCs and SoundBlaster/Adlib is within the demoscene, where people like John Valtonen (of Future Crew) could pull. We were all watching and listening in total amaze.
Not only is Frank's work on Dune 2 and 2000 considered iconic soundtracks, but so is the original Dune, with its more eclectic style by Stephane who sadly recently passed away.
I'd also add that the new Awakenings game has excellent sound design.
On film, the 1984 Dune movie has an excellent soundtrack as well, with Toto's iconic songs and with Brian Eno's theme. The new movies have a good Hans Zimmer soundtrack, but I would argue a bit less innovative and more safe than the above scores.
