I always struggle with writing battle/fight music. Here's my latest attempt (from Penultimate Fantasy III). On the one hand, using the NES limitations made things simpler because there was only so much I could do. But on the other, there was only so much I could do. Making this a convincing rpg battle theme was hard enough for me, let alone making it an interesting tune instead of a collection of tritones thrown together for easy dissonance.
