It's no secret that the Halo franchise has seen better days. Debuting as Xbox's flagship system seller all the way back in 2001, Halo entered the gaming industry as one of the greatest Sci-Fi video games of all time, and its legacy somehow only continued to grow as the years went on. Halo 2, Halo 3, Halo 3: ODST, and Halo Reach weren't flawless games, but they've gone down in history as some of the greatest Xbox games ever made, and considering the franchise's current state, it's easy to see why so many fans long for a return of those earlier entries.
