A very easy way to beat the game is to be the ninja's then keep capturing their cities until your strong enough to capture Echigo the Samurais academy then just get a bunch of samurais and put them first i captured all the cities and i think i only lost 1 or 2 of them......oh and make sure to get high intelligence and dexerty too
