This game has the absolute most greatest opening CGI I have ever seen in my entire life.
It is essentially a movie, of Samanosuke, the samurai, who has to stop this evil Japanese warlord from taking over the world with his demon forces. However cheesy it may be, it has to be the coolest intro of any game.

You might have to sign up and it is a large download, but worth the wait.
