Thanks for all the great replies, all of you!
Hessi (in reply to quote): That was badly put by me. What I really mean is that I am seriously considering a game design career.
Also you mentioned that "getting into the game industry" isn't hard at all" which is more then I knew. It's mostly that I'm unaware of the ratio of available positions:available artists (which is pretty important). Thanks for your reply.
Skjalg pretty clearly shows the different paths. It's a question of gaining a broader knowledge that is clearly printed on paper or to specialize and have your knowledge shine through your work.
Anyway, in consideration to all your replies I've come up with a... strategy, if you will. I'll finish "gymnasiet" (high school) this spring and after that I will either spend six months or a full year honing my level design skills. My portfolio will grow and I will attempt to apply for a job. If I'm unsuccessful I will go on to higher studies in the spring or fall next year. If I get a job I will miss out on my education obviously but as luck would have it I live in Sweden which means I can pick it up anytime in the future. Yay or nay?
