Well, I do post-production, so although I create music as a hobby, what pays the rent can be anything and everything. For the past coupla months, I've been putting together some great compilations of Latin music, but I also edit and master classical music. I also have several singer/songwriter clients as well as producing recordings of stage shows for Hackney Empire Music Trust among others. I'm not into rap or hip-hop or trance, so don't put myself out for that...
Plus, I have worked on major Hollywood movies, SFX, music etc. (bits of Harry Potter, but I did a lot on Reign of Fire with Patrick Bale and Matthew MacConaughey, that was a great blast, I even stood in for Matthew, well his voice anyway!)
So, I don't find as much time for games as I'd like, but they're a major part of my leisure time, such as it is....
Free grub sounds like a great way to maximise your hobby...
