Okay folks, it's time for a revelation on Shogun II Total War Campaign.
The creators, since the start, have placed a great emphasis on understanding "Sun Tzu" and his "Art of War." I've read the book over several times and my paperback edition is laying right here on my desk. However, as much as I tried to apply those principles to the actual game, nothing really "worked" in a decisive way.
Then I watched "Battlefield Generals" on the Military Channel.
This was about two weeks ago, and I had just come from doing hard phsyical labor so I was in no condition to look at it "philisophically". Anywho, it was talking about the Japanese invasion of Malaysia campgin and the battle for Singapore during World War Two. It said that Japanese forces would (and excuse me for paraphrasing) "...get into light ships and move their forces behind enemy lines to where they least excepted them, and would trap the forces on the other side in a pincer movement along the costal corridors..."
So just today, I launched Shogun II Total War and started as the Mori. And suddenly, it hit me. As I gazed over the map, I realized that most cities lie on the coast and that I had been doing it wrong. Instead of getting an ultimate navy to strangle the enemy, one simply needs to send its force AROUND those pockets of resistance where the enemy has its most strength, and take the castles it has the fewest troops in. Thereby strangling off the enemy's source of income and thus, their ability to wage war. Until you have effectively trapped them.
All in all, I have tried this and the game is.....coming along quite well. I won't say that there haven't been drawbacks, because there have. But overall, with all that's happened, I am steadily progressing Eastward towards Kyoto.....
Just though I might add this for any other struggling player.
