The sites I frequently visit (like daily): Here, Lucky's site, VoodooVB GameDev.net Gamasutra occasionally I visit flipcode as well, there are some really smart people there. GameDev.net has heaps of really good articles and a really good set of message boards (ie they have people there =) but it is mainly focussed on C++ (well, the people there are). Gamasutra is the web site brother of the Game Developer magazine, it is for professional game developers but all the articles there are really good and in depth. But a lot of the time, for things such as BSP trees or Quad Trees, you might also want to try some pure maths sites and see how they fit in outside games and then go to a more game specific one. hth
