I am interested to learn video games development. Where would you start? I am thinking to try to do some homebrew on my Nintendo DS. I am experienced in embedded software development in C. What would you do next? Is it worth looking for a specific degree? As anyone experienced an online degree? Or is it better to invest time to learn by myself?
I'm no expert on this at all but basically I would answer yes to most of your questions. Start trying to teach yourself. A games related degree is valued by the community but not necessary. If you can create a few demos yourself or with some friends this can demonstrate a great deal to prospective employers. You already know one of the key technologies. Just get started and get what ever you do in front of as many eyeballs as possible.
