About half of this soundtrack consists of updated versions of tracks from Klepacki's excellent Dune 2 soundtrack. He claims that the way the tracks sound in this is how they were supposed to sound in the first place.
Simply put, he's wrong. I don't believe a word of it. Aside from the boring production, he's changed notes, chords, and generally made everything sound much more 'normal.' None of the new material is worth mentioning, either. It's just entirely bland.
So I suppose it fits the game perfectly. Just like the game, it's not unpleasant, but it's not memorable, and to be honest, it's not worth your time.
