At this stage I already have what I'm talking about pretty much formulated with my head. However, I think I will stick to game scores that I know and love (such as the latest Blizzard ones, by Jason and company,
Arcanum, by Ben Hogue, and
Morrowind, by Jeremy Soule).
However, I will use your advice about the importance of music in games, with regards to fight sequences and . . . well, everything.

I have a lot to talk about, and it's all buzzing in my head. So I'll let you know how it goes tomorrow.
