There are hundreds, if not thousands, of game development sites on the Internet. Some are good, some bad, but in my personal opinion, all in the following list fall into the first category. Not all of these are related to DarkBASIC, but you will find a lot of useful information from game development discussions and articles not specifically written for DarkBASIC. The important thing is the understanding of concepts, so you should be able to glean useful techniques for your games from any tutorial or article.
