It's the same no matter where you study - teachers aren't interested in what else you've coded, they don't have the time - they are only interested in if you can do the course work.
But maybe that's for the best. Nobody really gets to be an indie developer full time, not until they start making actual money with their projects, and no matter what a videogame course might promise, it just wont happen... professional development houses expect a degree or a shedload of experience, you don't really get these from videogame courses.
What strikes me is that you say ''I believed the hobby will become all of my life when I reach present age. but It was broken into pieces''
So can anyone name a famous/successful game developer who owes it all to the college they went to?
Higher education tends to be about investigation and solving skills, using standard practices and an ability to adhere to requirements... nobody said they were designed to produce individuals

Game development is not strictly a career, it can be a hobby, it can be a side job, it can be something you do instead of going on holidays, or when your ill. College should teach you the skills to be a better developer, not how to work on your own portfolio.
But the main thing is that it's a fairly even playing field - 1 guy working on his own might make a lot more money and reach a lot more people that a whole team - it's happened a few times, and even fairly small teams like Vlambeer are kicking ass. Notch didn't go to game developer class, and he's worth more money than some countries!

I am the one who knocks...
