I develop my own games for the purpose of building up a portfolio that will end up getting me a job after college. Now, my problem is that I don't do my own art/music/sound, so I rely on open source stuff generally. More specifically, I get art/music/sound from many, many different sources and I'm not always sure if it's considered open source or not. SO:
For a non-profit strictly-portfolio game where I will provide the source code upon request, is it legal to use open source images/sound/music (without giving credit - I don't want to get slammed for missing someone in the credits).
Also, if you modify an existing image, sound or music file, is it now your work? Their work? Partly both? How does that work? What if you completely replicate it from scratch? Is it still considered their work?
