Okay the real reason I am getting involved in 3d and animation is for the simple fact, that I want to make video game graphics.. I know it will be a hard and long journey but its something I am interested in!

I was hoping someone here has had a little experience in this field that could point out the key points and the things I need to learn/know about game design.

Also if I wanted to create a world/zone for the characters to walk through what process would I go to. (this question could take some time explaining, feel free to ignore it if I am asking to much).

Thanks,
Robert
