MKGaming - "Let’s give praise where it’s due. Call of Duty 4: Modern Warfare pretty much single handedly changed first person shooters on consoles. It bought us unlocks, perks, loadouts and much more, whether you like these things or not you have to admit, it was a bit of a game changer. Modern Warfare came out in 2007 and every year since we’ve been exposed to another Call of Duty title, with development switching between Infinity Ward and Treyarch. Critics have accused the Call of Duty series of being stale with the engine and gameplay almost being identical year after year."
