For all you guys that think this game is boring, you have a lack of an Attention Span. And for those of you that think it is hard, you are supposed to THINK. Ring a bell?
Tipp for beggining: Choose Aomori (Right below topmost region) and Pick a good defense (I reccomend Defensive Cannons or Barrier) Buy 5 swordmen and 4 Bowmen. Next turn, Immediately attack Hokkaido. During battle, hit the God of Power Strategy and click the thing below your groups oof troops. You will win the battle. After this you can figure out :P
