As the name suggests, it's second world war-themed. But there's a twist: as well as controlling US forces to recreate famous Pacific naval battles, you can rewrite history by leading the Japanese campaign from Pearl Harbor onwards. Success – as either nation – requires the mastery of everything from fighter planes to submarines via battleships, destroyers, scout planes, etc, in action that blends arcade style shoot-em-up – roaming the skies or waters to blow stuff up – with deeply involved, nigh-Mensa-level strategy where you control hundreds of units. To blow stuff up. A vast, and generally impressive, experience.
