LOL, playing Okinawa, got to top notch military, got that perfect combination enough for 1 army, now i have 1 province at the tip, with a castle standing against the whole of japan. Have barely lost a single soldier...
Starting 2nd at the top makes this game quite easy, get a cannon in your main province, take the top province, then continue downwards focusing on soldiers. 5 medics, 10 snipers and 10 swordsmen make an awesome army, using the freeze powerup. Building magnets all along the way.
