The Blending of Music and Games
Gamasutra has an opinion piece by the 'father of music games,' Masaya Matsuura, who questions the evolution of video game music (or the lack thereof) as the industry's technological advancements give rise to the capability for greater complexity. "Most games these days seem to use gorgeous orchestral soundtracks. While these large-scale soundtracks may generally be lovely to listen to, if we really think about it, isn't it all a bit lacking in imagination? Thinking about it from a simplistic visual perspective, while films are basically just watched, games are interactive." He also discusses the predilection for games to encourage "competitive fun," as opposed to "cooperative fun." GameSetWatch has a related article which talks about how excellent musical scores can help to create an emotionally charged experience, rather than simply occupying one's mind for a time.
Having the sprawling orchestral arrangements is nice, but as a video game music fetishist since the NES days I know that the songs big and small rely on catchy motifs to motivate the gamer and stick inside their head. You think the Minibosses gathered crowds by playing orchestra?
Many classic NES games have captivating, moody music - Wizards and Warriors' soundtrack is +1 underrated. Long-running series such as Final Fantasy and Castlevania have used some of the same titles and motifs throughout their entire series.
Hmm... the Gamasutra article struck me as a little pretentious, but maybe that's just because I actually like big orchestral scores for games. Some of my favorites include:
Wing Commander: Yeah, it was low quality midis, but at the time, it was jaw-dropping. It felt like you were playing a Star Wars movie on your PC and the soundtrack was a huge part of that. From the intro sequence, with the theme that was more than a little reminiscent of the ST:TNG theme, through to the battle music and the Kilrathi theme (also used for fun in Ultima 7), the music in the first 2 games was awesome. Who can forget the cheesy-but-classic "scramble" music that played before every mission?
Star Control 2: Each of the many alien races in the game had its own music and this played a huge part in setting the atmosphere for every encounter. The Ur-Quan and Yehat music, in particular, have stayed in my mind to this day as examples of great videogame music.
X-Wing: The Lucasarts I-Muse system which changed the soundtrack to reflect the progress of the battle was revolutionary. The audio cues from the music would directly influence your battle tactics. You knew that a few bars of the Imperial March meant that trouble was headed your way.
Pretty much anything Final Fantasy: Ok, perhaps the soundtracks haven't been universally stellar, but pretty much every Final Fantasy game has had a few tracks worthy of real notice. FF6's Overworld theme, FF7's Cosmo Canyon theme (and, of course, One Winged Angel), FF10's "To Zanarkand" and FF11's Memoria de la Stono all stand out as some of the best pieces of video game music ever.
Super Smash Brothers Brawl: The fantastic main theme, which is used appropriately throughout the story-campaign, does a great job in adding a touch of gravitas to what could otherwise be a rather lightweight story.
