Choi adds that while there are many parallels between videogame and movie soundtracks (such as title sequences, recurring character motifs, and narrative cut-scenes), gaming's non-linear, participatory nature means that the music strikes a potent chord in us: "The power of videogames lies in the fact that you actually become the protagonist of the story; although the story itself may have been predefined, you control how and when it unfolds," he says. "It's precisely this power – that you've been given to interact directly with the experience – that makes videogames stand apart and continues to excite me as an artist."
