Best Xbox Franchises

I am looking for all of your opinions of the best franchises of all time. In order to be in the list it must have at least 2 games in the franchise.

1. Halo

   

   This game is based off of a character named master chief and his AI Cortana. They battle an alien species called the covenant.
