Recently, Gamedev.net posted a series of interviews with the IGF finalists.

While I haven't read them all myself yet, those I did read where very informative, so I thought I post the link here (Clicky, [size=9px]and scroll to the bottom of the page[/size])

One in particular I'd like to mention is the interview with the creators of FizzBall. This interview is less about the game and the process of creating it, and more about bringing it on the market, their experience with portal sites and sales in general.
