Hi PilotMatt,
Well, the good news is you DON'T need a degree in music to make a living at it! That's not to put you off studying, it's important to be open-minded about all styles of music and to look into the nuts and bolts of how music works - but you probably knew that!
I'm listening to your music right now on Myspace and I really like it. I can tell you have a strong link with music and you undoubtebly express that in your performance. Elois is really nice (listening now) I love that kind of music (check out DroneZone radio if you haven't already)
What you need now is probably a few pointers rather than the "whole shabang" from a musicologist. Yes, if you learn about counterpoint, atonalism and all that it will definitely give you a rounded knowledge, but you said you wanted to write music for games and film and that's different, very different!
Film music isn't about the music - it's about telling THE story. Film music isn't about a certain cadence or using counterpoint correctly - it's about telling THE story. That's all I really have to say on that point..
If you haven't scored for anything yet don't worry! There are resources all over the internet. If you're just starting out then don't expect to be paid straight away - build your show reel up with student projects and no-budget independant projects. You'll gain experience, improve your skills and you'll also have something to show to the next client and convince them you're the person for the PAID job.
Here are some websites you might want to check out:
www.mandy.com - lots of film projects / student projects and it's free to join.
www.talentcircle.org - same deal as mandy.com
www.shootingpeople.com - you have to pay for this but it's a good way to meet people and there are always postings asking for composers / music.
www.scorecastonline.com - I don't think they have jobs, but there are LOADS of really interesting articles written by 'working' composers.
I can't really give advice on games as I have very little experience in that field. Again, work for free on independant no-budget projects - just make sure with games that they will get finished. There's no way you can know that, but maybe just an evaluation of the people involved (have they completed any projects before? do they seem driven and serious about what they do?)
Anyway, I like your music and it's very soundtrack. Keep developing your style, listen to LOTS of music but spend more time composing than listening - find that balance between being aware of others music but not being too influenced.
Learn all about the technology too, because we're expected to be engineers, mixers and producers as well!
Hope this helped a bit, good luck!
