Yeah, yeah, I know I told I would be away for some time, but yesterday found this while I was searching for additional reading for one of my exams.
The page in question is agilegamedevelopment.com, a site maintained by Clinton Keith, chief technology officer and lead engine/tools programmer at High Moon studios. A very interesting read (don't miss his blog!)
As an extra, found a link in his blog to a conference by Mary Poppendieck entitled "Competing On The Basis Of Speed". As Keith says, "one hour of solid gold".
Before I forget, here's the Link to the conference.
