At this point, Assassins Creed is more of a gaming institution than a simple series. With almost two dozen titles in just over a decade (plus movies, novels, and more), the franchise has developed its own arcs and stories that go well past the events portrayed in its code.
While the series struggled under an accelerated release schedule some years back, Ubisofts tentpole franchise is on a more solid pacing again. That means a return to what Assassins Creed does best: expounding on and remixing prominent game design ideas and serving them up an aesthetic and conceptual cocktail. Odyssey, much like last years Origins, takes ideas from its best contemporaries and reassembles them into a new whole.
