7. The war between the Templars and Assassins
Assassin's Creed players were surprised to learn that the 2007 game was bookended by a story set in modern times, and it wasn't until Assassin's Creed 2 that the tale of the ancient feud between the Order of Assassins and their evil Templar rivals really began to take shape.
The conflict is more than just a rivalry, though. It's a war. And it reminds us of a different war: marriage.

We guess no one ever told her—Love is a Battlefield.
