War in the Pacific: Admiral's Edition makes a few changes to the gameplay that improve the experience you remember. The new world map covers half the globe in 40 km hexes that do a good job of breaking up the map into smaller segments. New combat modeling gives you an even greater advantage to the Japanese airpower in the opening parts of the War in the Pacific. This is much more realistic, and indicates some of the problems American pilots had to overcome in their battles against the Japanese. The naval operations are easier to execute because of added waypoints, mid-ocean intercepts, new ship classes and an improved ship upgrade system that is useful and satisfying. They have also added engine versus system damage in this edition, new ship art, and realistic port limits for ships, cargo and repairs on your ships. They actually did a pretty good job of adding useful features and things that improve the gameplay.
