I should start the sharing by saying that I've worked with good friends, fellow students (back in high school), as well as finding someone through posting flyers around at game shops. I am saddened to say that none of my collaborative experiences have panned out; most folks let other things in life take priority. The only game I've managed to finish & release started with an artist and ended text-based.
It's also quite troubling/surprising that since travelling the country for the better part of the last two years through the medium of DIY music and touring I've found zero folks who pursue game development, even on a casual level.
