5. An Inconvenient Truth
Don't tell me you weren't surprised . Every person on earth who played Assassin's Creed II was surprised. So, you're in the Vatican, about to kill the pope - a fairly weird scenario in its own right. There,we expect the game to meet its end with Ezio finally getting revenge on Rodrigo Borgia, the man who killed his family. But that didn't happen. First, he lets the most evil man on the planet escape with his life. Second, he meets a Roman Goddess in a secret room - didn't expect that one. Let's rewind that a bit. So, after letting Alexander VI go, he walks further into the 'vault' and discovers a hologram of Minerva, the old Roman Goddess. She tells him, and Desmond who's conveniently spectating, that she and many other 'Gods' were part of Earth's first civilisation, who were ultimately destroyed by a catastrophe caused by the sun. She also warns them that another disaster will occur. If Desmond can't find certain 'temples' before the apocalypse, the world cannot be saved, and will fall once more. So, why is it defining? Well, this moment shapes how Brotherhood, Revelations and (most likely AC III) will be told. Truthfully, there wouldn't be much point in Assassin's Creed games if this plot was not created. Would you be as interested if it was just 'Assassins v Templars' all the time - like repeating a bad Call of Duty sequel? This gave the series the freshness it needed, just as the whole game of AC II did. It didn't necessarily define the Assassin's Creed franchise, but it defined its most valued possession - its story.
