It is not quite the same as the game. Although, they were both written by the same guy, Ukyo Kodachi. He also wrote the 'Frontier' and 'The Ride' novels. He incorporates those as Grace comes from the 'Frontier' novel timeline, and 'The Ride' characters Maris Stella (loli cyborg pilot of the YF-27-5) and Brunnhilde (the sentient control AI of Chelsea Scarlett's Variable Fighters) are in the 'Macross 30' novel.
