Fortunes can change quickly as last turn's power broker becomes this turn's goat. Players bid money for turn order and for hiring the ninja, as well as the usual buildup of forces. Although not a very hard game to learn the depth of the game is excellent. Players have to think several turns ahead to get on top and stay there, and until the competition is taken down a few notches, it's anyone's game. The battles have a very unique feel to them that captures some of the essence of the game's setting very nicely.
Games can take a long time to finish however, but the fast-play rules help somewhat.
This one is a winner, no doubt. But, goofy premise aside, this is a really good game. The system starts the US player off relatively weak, but able to grow in strength each turn. Conversely, the invaders are strong to begin with but attrition will do them in if they don't win a swift victory. Initially, everyone thinks the invaders can't lose, but when the US tactics are figured out it goes the other way.
