Finishing up the last seven days, it's time to recap the top full-length features of the past week on Gamasutra, plus extra features from sister edu site GameCareerGuide - and there's some rather smart stuff in here.

It's headed by a look at innovative casual/indie game design and a pretty neat piece on mixing audio for games, as well as a Shane Kim interview and Matt Matthews' customary NPD analysis goodness, as well as a couple of GCG pieces topped by a postmortem of good-looking Xbox Live Community Games title Trino.

Cha cha cha:
