For all Total War fans or anybody who likes commanding vast armies to die on their enemies swords for your amusement you might want to check out the Shogun 2 demo which is available now.  If you have played a Total War game before a lot of the mechanics will be familiar but that doesn’t stop the quality of the games theme shining through,  you can play through a tutorial campaign in the demo including some sea tutorial battles and a single historical battle once you know what you are doing.  Go on,  get your Samurai on!
