PlanetXbox360: "Whether you love the franchise or hate it, Halo is undeniably the lifeblood of Microsoft's gaming console. The original Halo not only propelled console first-person shooters to what they are today, it served as the most compelling reason to pick up and Xbox. If it wasn't for Halo, the original Xbox likely would have failed, resulting in no Xbox Live and likely no level of online gaming even close to what we have today. Sure, games like Call of Duty and Battlefield are stealing some of the spotlight, but no other franchise can even come close to accomplishing as much for the console FPS genre as Halo. As such, it deserves recognition as the best console first-person shooter franchise of all time."
