Just about everything you could possibly need to know regarding game development can be found on the Internet. But then, you probably already knew this! Search engines may be your friend, but they can often return a bewildering array of hits that may or may not be appropriate to your game development needs. I’ve listed in this appendix every link from my own personal bookmark folder of game development resources, as well as some more recommended by friends.
Of course, this is certainly not an exhaustive list. However, the sites listed have very long histories on the web, so most are not likely to succumb to “link rot.”
I think you will find these resources useful.
