I just read a great post from Darius Kazemi on his Tiny Subversions blog about writing your resume if you're applying for a job in game development. It has specific advice.
He recommends you work on game projects - what you learn from that is worth more to the game company than most things you learn at a part time job.
So this summer - don't just lay around - even if you are reading great literature or playing all the new games. Create games too. Find some people to work with. Get some experience worth putting on your resume. Because you want to go to the Game Developers Conference and South by Southwest interactive (SXSWi).
