Chris Vrenna's breathtaking soundtrack for American McGee's Alice didn't make the guild's list, which is a little disappointing. I've had the Alice soundtrack for nearly two years, and it still sends shivers up my spine. It's been a while since a movie soundtrack has had the same effect.
The composition of in-game audio has improved quite a bit over the years, and I can only hope better audio quality follows. With a number of true 24-bit audio cards on store shelves, it would be a shame if games kept using relatively low-quality MP3 audio. Some games are beginning to ship with an extra CD containing super-high-resolution textures for those with plenty of graphics horsepower, so it shouldn't be a huge leap for developers to serve up another disc with real CD quality audio for those of us with sound cards, speakers, and ears good enough to hear the difference.
