For anyone considering this book, or it's closest competitor (that I've seen) "The ultimate history of video games.", my advice would be to buy this one. This book gives a much broader story of the development of video games, with much more in depth details of European developments (British, French and the Demo scene are well covered). As well as some things I had not previously encountered (having been a gamer for 30 odd years and following retro games for about a decade), like Hasbro's aborted Nemo VHS based console.
There are a few error I've spotted (The protagonist in Half Life is GORDON Freeman, not George). But a few quibbles aside an enjoyable and enlightening book.
