Compiling the feature-length stories from the Gamasutra network, here's the top full-length features of the past week on big sister 'art and business of gaming' site Gamasutra, plus the new GameCareerGuide pieces that debuted last week.

Some of the new pieces that debuted despite E3's advent included interview with the Mafia 2 and Puzzle Quest 2 creators, plus a chat with OnLive's Steve Perlman, analysis of audio in games and stencil shadows on the iPhone, plus the latest GCG pieces.
