One improvement I would like to suggest would be a list of game development resources, i.e.: raytracers, modelers, SDKs, wrappers, gfx engines, texture libraries, sprite libraries, utilities, etc.. There is tons of stuff out there made for game development that people don't even know about. Like, I just found out about MathEngine today (which looks pretty nifty).
I know that in some ways I'm describing the game development search engine, but, I've found that it provides too much information to sift through, it would be nice if those sites were compiled under a topic structured list and rated. Thats it.
