this video explains the basics on several key topics in shogun 2. This is for informative purposes for new players trying to decide whether to buy the game or not.
I do like gunpowder warfare and it's some of my favorite types of warfare in history. (Though the Chinese warring states / Unification Wars were my absolute favorite)
I'm not to quick to judge a game till I actually play it for myself. So I bought shogun 2 and it was great. I suggest this game to others but I don't think most will be comfortable early into the multiplayer section of the game.
Just be patient and respectable to others online and eventually you'll unlock and gather veteran units to gain an edge against an experienced opponent. I still lose daily but not often. So the gameplay is balanced enough to where any random opponent actually forces me to stay on my "A Game".
Good Luck and Have Fun Players.
Salute!!!
