Vidya development

I'm being serious, this isn't a troll thread or whatever.

Im interested in developing games using C++ and OpenGL. My question however is, where do I even start? In a cg artist, so rigging/animating low poly models and creating landscapes isn't an issue. Can I even learn all this without going through a college CS course? What are the things I need to know (optimization, vector math, etc)? Any recommended books?

Better don't.
there already are enough unimaginative games out there, no need to have another one. On the other hand if you already had a concept, knowing what you need to accomplish you wouldn't be asking these questions.
