Unity should have been the end. Any other video game franchise, it would have been. It was that bad. Assassin's Creed III, the previous low-water mark in the series, was a masterpiece in comparison.
It's a measure of just how much momentum and goodwill this 'secret history of the human race' saga has built up over the last decade, that it (barely) survived both that and last year's Michael Fassbender/Marion Cotilliard cinematic abortion. 2015's AC Syndicate did a lot to restore, if not the luster, at least some credibility.
So now, after an entire year longer to make than all the other games have had, and the crew behind Black Flag helming it, and now that the historic re-enactments have come too close to our own present time, we're reversing course and (in a soft kind-of-but-not-really-reboot) heading alllll the way back to 49 BCE, the age of Cleopatra (and the imminent rise of Julius Caesar's Rome). Back to the very first Assassin (a Medjay warrior named Bayek), his eagle sidekick Senu, and a man (or is it men?) in a blue mask.
And the mystery of just what lies under the Great Pyramid...
