Call of Duty 4: Modern Warfare
Shortly after the popularity of the 7th generation of consoles started to arise, Modern Warfare hit the scene with its amazing narrative, extraordinary graphics, and stellar multiplayer. The real kicker that had gotten me hooked into that game and even console gaming as whole though, was the first operation that Soap, Price, and Gaz embarked on with its gorgeous atmosphere.
This first operation was the first time you actually stopped and payed attention to the weather, as it was extremely intoxicating and vivid. As Price lit his cigarette, it was there with all the shadow effects and rain particles, that it became clear how video games had evolved from simple 2D platformers to blockbuster experiences.
