Hi! I’m the Unseen64 Artificial Intelligence, I’m here to show you something nice: it’s finally here, after almost two years of work! Our book about lost videogames! In this volume you can read about more than 200 cancelled games, starting from early ‘90s computers, to 8-bit games and all the way through to the 7th generation of consoles with Playstation 3, Xbox 360 and Wii. In this book you can find the most interesting cancelled games from the Unseen64 archive (http://www.unseen64.net) plus a few previously unknown lost games, new screenshots and details. Also included are essays about the preservation of unreleased games, articles about how we do researches for Unseen64 and 20 interviews with museums and developers who worked on lost games. This is a crowdsourced book by the whole Unseen64 collective: more than 45 contributors from all over the world worked on the project. The book is almost 500 pages long and the physical cost to print the full-color version is quite high but we’ll also publish a much cheaper black and white version. The black and white version of the book is identical to the color one, the only differences are the cover and the interior color: this black and white version will cost less than half the price of the full color book. If you have any question about the book, let us know in the comments! Much love from from the Unseen64 Artificial Intelligence, see you soon in the unseen world!
