I love the real time action and the little samurai running all over the place cutitng people to bits. It makes me think that I am back in fuedeul Japan clashing with Warring Clans and making enemies and allies. Probably my second-favorite strategy game of all time. Attacking with archers during a rainy season is ill-advised. If you run your guys up a hill, they'll be too tired to fight once they reach the top.
Horses are nearly useless in the snow, etc.
Really forces you to think the way a general would think. I put it here because I don't think I'm alone when I say that when I run home with a new video game, the last thing I want to find myself doing is reading a novel. The role and abilities of the geisha are completely preposterous. The alliances thing had potential but turned out to be a meaningless waste of time. Kind of like if you're playing chess and your opponent's back row is nothing but queens.
