I've made a simple program where you fly around, with 3d objects floating about. A primitive space-sim I suppose.

But I don't understand how I could adapt that to a Quake style game.

Could you please point me in the right direction on how I should go about attemting it.(like books, web-sites, tutorials, etc.)

Also, I'd rather NOT just use a pre-built FPS stlye engine. I'm really trying to learn this stuff.
