Is a Ph.D equivalent self-education possible? I want to be a computer game programmer/designer and I want to know if I can teach myself physics in my spare time. It may take me 20 years, but I am determined to learn everything there is to learn about physics. I would become a physicist if I didn't want to be a computer game designer more. Right now I just think I would be more happy (and wealthy, which doesn't hurt) being a game designer.
