6. Call of Duty: Modern Warfare 3
Developed by Infinity Ward and Sledgehammer Games, Published by Activision
Regardless of how you feel about iterative game development on an annual timeline, cranking out a Call of Duty game every single year has certainly benefitted Activision. It's also benefitted the legions of gamers wholly obsessed with this franchise, and the latest entry, Modern Warfare 3, didn't fail to deliver to them everything they're used to: high production value, addictive multiplayer and gameplay tighter than Ghost's skull mask after his mom accidentally put it in the dryer.
