You can play through most stages using multiple characters, each providing a unique experience. While playing with other characters is generally less fun, it does give the game substantial replay value. Their stories intertwine, giving the game a cohesive quality. Spicing things up are snowboarding, airplane shooting, and pinball stages. Sonic Adventure is surprisingly long, and just when you think it's over, you're off to a new stage. There's even a virtual pet-style "Chao" game you can download to your VMU. The musical score is eclectic, ranging from the heavy metal of the intro to the mesmerizing African beats of the Mystic Ruins. The character voices are less appealing, and it's unfortunate they were given voices at all. Even so, this ambitious game is a triumphant blend of fast action, simple controls, and stunning graphics. Even ten years after its release, playing Sonic Adventure is a breathtaking experience.
