I am researching into the game design or development process for a class of mine in college. Would anyone be able to point me in a few (or many) good, or at least different, directions as to where I can find credible information on this process? Websites would be preferred (as it is easiest to access) but books (and where I can find them) are more than appreciated.

I apologize for the vagueness of the question but I am looking into the entire process, from concept to shelf in the store and when I go to search for information, I am simply bombarded with game dev schools, not actual information.

Thanks in advance.
