I think for a game like Alganon some of the most important things music does is to support the mood of the game, keep out of the way of gameplay, and don't drive the players crazy with repetition. Some of the ways that I do that is with a lot of variety even within a piece, moving from thematic sections to very ambient sections and getting away from some of the more used musical techniques and sounds that have permiated games in the last few years. Also by bringing in some different techniques to create some interesting textures.
In composing the music for Alganon, I not only wanted to create a dramatic score that fit the mood, but used instrumentation that matched, the culture or ideals of the cultures from that area. For instance the areas controlled by the God, Xukiss, like Teldis, the God of industry, I used almost mechanical, industrial repitition but with an organic texture.
The Kujix music has almost angular melodic ideas and strong percussion to match their agressive nature while at the same time a beauty that matches their rich, old and developed culture.
