This is notionally a biography of a video game, and apparently a real one according to Google. I guess the Boss Fight conceit is similar to the biographies of cities that were common in the 1990s (cf John Birmingham's Leviathan), and distinct from Michael W. Clune's Gamelife, which was mostly about himself.
But as always with Kobek, the meat is his cultural criticism. His target this time is the general state of Britain in the 1980s under Thatcher, using nepotism in the computer industry of the day as a vehicle. Francis Spufford covered similar ground in Backroom Boys, and even discussed the Elite video game. It's funny and erudite, and the only thing I saw him miss was that Acorn went on to wild success with the ARM architecture, while Amstrad and Sinclair have pretty much vanished. I guess there was also scope for linking this stuff up to the Raspberry Pi. Like Dark Shadows, Alice Cooper plays an overly passive role in the game and this account. We get the moral outrage of the day, and a fascinating but undercooked jag into the demo scene of the late 1980s and early 1990s, as well as some stories about the obsolete computer designs prevalent in eastern Europe up to recent times. The game itself is graphically hellish and unwinnable. Some brief searching made it seem to me like a low-rent version of the Apple ][ game Montezuma's Revenge.
... and of course Boss Fight have a book on Mario Brothers.
