A list (with most games available for download) is here. If you're going to GDC, be sure to stop by the IGF booth and play for yourself anything that you can't play now.
Students wishing to win the IGF some day should take a good, hard look. This is the bar you need to meet or exceed as a student project.
Note that you do not need to be brilliant at all aspects of game development. Crayon Physics and Poesysteme have rudimentary graphics at best. The Misadventures of P.B.Winterbottom was done using some very simple scripting in Flash. Mayhem Intergalactic isn't particularly original game design (it's basically a "mod" of the board game RISK).
I do not point this out to put down this year's winners. All twelve are outstanding games (and I judged some outstanding games that did not make the list), especially considering that they are student projects. Rather, I say this as a word of encouragement to those students who are intimidated. Yes, the bar is high. But if you can truly excel in one or two areas of game development, even if you are lacking in the others, you've got a shot. Design and create the kind of game that really shows off your strengths, rather than complaining about your weaknesses.
