21st Century Game Design
This is a great game design book. Unlike other game design books like Rules of Play, this one is completely market-oriented, analyzing data from field research and combining with psychology patterns of behavior to provide a very interesting framework to design a game for a target audience.
The Ten Faces of Innovation
This is a book about people – the fundamental force behind market innovations. Through in-loco experience, Tom Kelley has divided the kind of attitude necessary for an innovative environment into 10 archetypes that every company should have among ts staff.
Agile Software Development with Scrum
This book explains in a very fast and simple way the methods of Agile and SCRUM project management. There are other good Agile / SCRUM books out there, but if you want to a fast introduction and a book simple enough for other non-Scrum Master members of the team, this is the one.
You forgot Rules of Play.
No, I didn’t. Rules of Play is good but too much game-designer-centric. 21st Century Game Design is market-centric, which is what really matters to keep a game company healthy.
