<p>Halo is one of my all time favorite video games series. I've made this collection in honor of the original trilogy.</p><p>The series focuses on the main character, Master Chief, as he battles to save the world against the alien covenant and flood.</p><p>The first game in the franchise, Halo: Combat Evolved, released on November 15, 2001 on the Xbox and by 2002, 1 million copies of the game had been sold. Since it's release the franchise has been extremely successful. Since the first game's release, 11 more Halo titles have been released. These have been some of the best-selling games of all time, and for good reason too.  </p>
