Or, what can you bring to the development of a video game?

I'm talking about something that's more than a hobby. Maybe an education in the subject. Maybe a secondary skill set. Maybe your career. Maybe something you're known for.

Examples include:
-Design
-Mathematics/Engineering/Science
-Art/Concept Art
-Music/Sound
-Computer Science/Software Engineering
-Writing

As for me, I studied guitar performance in college, and spent most of my (sparse) free time composing. I'm starting to think about writing some tracks for free use on byond.
