This new stand alone release based on the legendary War in the Pacific from 2 by 3 Games adds significant improvements and changes to enhance game play, improve realism, and increase historical accuracy. With dozens of new features, new art, and engine improvements, War in the Pacific: Admiral's Edition brings you the most realistic and immersive WWII Pacific Theater wargame ever!
I'm no programmer, but from what I understand I'm not sure the engine would support a map that changes over time during the game. If you want more roads, I believe there are some mods with different maps that include things like the Thai - Burma railroad.
The game is what YOU make it. It's not perfect, but it is pretty complex and very stimulating. Especially if you start playing other humans.
