November is a big month for the Assassin’s Creed franchise – it’s the first full month since the launch of the latest title, Origins, and it also marks 10 years since the release of the first game. 

That’s right, the Assassin's Creed series is 10 years old. No, I can’t believe it either. It makes me feel old enough to be an Animus ancestor rather than an Animus user.
