Hi all, I hope this is ok to post here (Admin, please delete if not and my apologies in advance - especially as this is my very first post)
I've been running the Games That Weren't archive for just over 20 years over at https://www.gamesthatwerent.com, and today pre-orders have opened for a book on the subject of unreleased games to mark the milestone. The Atari is covered quite a few times throughout (Arcade, Lynx, Jaguar + ST - including a lovely wireframe spread image of the Atari Game Brain), but overall it is a multi-format book and covers a wide range of titles from 1975-2015.
It's been written by just myself over the past 7 years or so to try and keep everything consistent, with many fresh quotes from those directly involved on the various games covered. I probably won't be doing another one in a hurry!
If you're interested at all or might know of anyone who might be, here is the link:
