The different steps to make a 3D video game

I know for openGL you needed to use other peoples software such as GLUT and GLEW which is what stopped me because I was afraid of getting tangled up in a bunch of legal issues.

This will help for openGL http://www.opengl.org/wiki/Getting_started

Also I'm pretty sure a lot of people will try to convince you to use a free open-source engine or make a mod instead of completely starting from scratch.
