The map and terrain is totally unfamiliar and makes for fascinating analysis. There are ZOC's, unusual for a Command game. Since the Americans can land anywhere and expand the beachhead, play is totally unpredictable and there is no telling what will happen. Oh yes, there is an Emperor counter the Japs want to keep out of American hands. Tokyo is worth political points.
Mt. Fuji is worth lots of points too.
Overall it is an immensely entertaining game. Last time I played it as the Japanese and won a total victory as the Americans sued for peace due to massive casualties.
