How I can become a GAME DEVELOPER at age of 15 ?

Answer:
In terms of schools, there are many these days: Digipen certainly, also Full Sail, the University of Advancing Technology, and others. Each of these are, I believe, well into bank-breaking territory. It's worth considering too that many come out of these schools with a lot of student debt and end up taking jobs at $10/hour in the games industry if they can get one -- not because they education is no good, but because there's a huge amount of competition for these jobs and they don't pay particularly well.
Other schools that I know of offering respectable game design courses or degrees include USC, Simon Fraser, RIT, Rensselaer, and Georgia Tech, among others. At the graduate level, the Entertainment Technology Center (ETC) at Carnegie Mellon is almost certainly the top school; USC, SMU, and others also have top-notch programs. There are many others, and more coming out all the time. The state schools tend to be much less expensive than the private ones, and this can add up to tens of thousands of dollars with no discernible difference in educational quality.
Oh, one other thing, since you are 15: in high school, you should be studying (and getting good grades in!) as many as possible of: math (through calculus if possible), English (writing and reading), psychology, theater, art, and of course anything you can get in terms of programming and game design itself (some high schools have these courses now). Playing a whole ton of games and not being able to speak or write well, understand how people think, etc., won't get you very far. (This is the part that parents most often like and kind of dismays the kids.)
