I make games, and usually I handle every part of my games (aside from 2D Art). I identify myself as more of a storyteller than the umbrella term that's a "Indie Game Producer". Because I believe that in the end, a Video Game is just a piece of media, and are meant to convey ideas from one to another.
In my experience of game making, I developed various content creation skills such like music production, localization and graphic design, sometimes I do commissions regarding those subjects to help those who may need them.
