The first three iterations of this game set new benchmarks in military realism, re-creating the precise action and sounds of World War II’s rifles and grenades. Call of Duty 4 applies the franchise’s signature detail and online play to contemporary battlefields, where you can kill bad guys with night goggles, copters, and 70 state-of-the-art weapons. And though it’s kind of awkward, philosophically speaking, to simulate contemporary war, we have to say that we’d rather do that than divert ourselves under the pat guise the Greatest Generation.
