I just finished reading the Hints & Tips for Video Game Pioneers book by Andres Hewson and Rob Hewson of the former Hewson Consultants. The book is very well-written and entertaining. It brings back the memories of when it all started on our beloved 8-bit machines. With all the background information and quotes, and interviews of many different people involved, it provides excellent insights. Many of the mentioned games I've not even heard of before. I recommend you buy and read it; it is worth the money.
