I'm admittedly kind of an old-school Nintendo fanboy, but I've loved some of the new wave of artsy indie games like Braid. Portal was really exciting too. I think a lot of really innovative titles are actually browser-based independently developed games.

Does anybody here program games? I've been goofing around with Flash for a class I'm taking and trying to figure out ActionScript, but I've heard a lot of people trash-talk it. What's the best as far as development tools go?
