Having enjoyed Napoleon Total War a great deal I was keen to play Shogun 2. At first I must admit that I was disappointed. I had ordered a game on DVD as opposed to Steam and found out I still had over 19 Gig to download! The second DVD in the case appears to have no use what so ever.
When I finally downloaded the game I found it a very different experience to Napoleon. It is a great deal more dynamic than it's forbear, infantry cover distances much more quickly. Individual mele battles are fought at a much faster pace than the exchange of musket volleys. Siege mode has been altered, you will often find yourself attacking or defending a multi layered fortress. Attacking at several different points will either give you more options or keep you on your toes!
Multiplayer battles are fought in three different ways: Campaign, Avatar and my personal favourite Classic Battle. I dislike Avatar mode as your unit selections are extremely limited to start with, around only 3 units! More often than not you'll be 'matched' against someone of a much higher level who there for an unfair advantage in unit choice.
I enjoyed the campaign mode of Shogun 2 more than Napoleon. Your ultimate aim is to conquer Japan and become Shogun. You can use a mixture of warfare, diplomacy, assassination and trade to bring this about. Overall a top strategy game with a few downfalls.
