To learn 3D game development with limited pockets, I guess you've tried many classic, free, open-source game development engines like TV3D (Truevision3D), OGRE and Irrlicht Engine. By contrast, the pros of TV3D are easy to learn and get started with; its cons are that it was built based on the ActiveX control and requires the RunTime DLL to be registered before running; OGRE is better than Irrlicht in that it has a capable and vigorous engine framework, and supports for extending new functionality in the form of plug-ins (this is better than Irrlicht); but its downside is that it's not easy to get started with.

CopperCube (successor of irrEdit) is a free 3D authoring editor, also the most user-friendly 3D game engine. It is developed based on the free and open-source 3D game engine - Irrlicht Engine (SWFZ Engine was rewritten from this engine too), and its essence is a simple, lightweight but powerful interactive 3D scenes designing software with concise and clear user interface, convenient operation, and humanized design. It is mainly used in the production of 3D application, 3D game, 3D website, and 3D animation.

Dxtory is a small game video capturing tool from Japan, specially designed for DirectX and OpenGL programs. In Dxtory, the video data is directly captured from a surface memory buffer, that's why it is so fast and only needs very little system resource.

I believe you must feel the same or similar way - not all favorite music can be found according to their names and then download or buy them. Especially the ones used in video as background music, which are often the classic. So the question is how to get them exactly and easily, legally? One solution is - extract (actually convert) them using tools.

MP3 Karaoke is a free, easy-to-use and pretty compact MP3-To-Karaoke (MTK) batch converter. With it in hand, we can quickly and easily (just one click, even drag & drop) convert our favorite bunch of MP3 music to Karaoke accompaniment. Thus we do not have to laboriously search for the rare music Karaoke any more. Just MIY (make it yourself)!
