The document criticizes Call of Duty: Modern Warfare 3 for making very few changes from Modern Warfare 2, only updating the maps and weapons, while keeping the same killstreak rewards system. It contrasts this with how Infinity Ward improved greatly on Call of Duty 4: Modern Warfare with Modern Warfare 2 by changing things up, but then failed to make significant innovations with Modern Warfare 3. Treyarch is praised for making each of its Call of Duty games, like Black Ops 2, feel distinctly different through new settings, equipment, visuals, and story campaigns.
