Katana is a spin-off of the popular Samurai Warriors series that takes the setting and turns it into a first-person sword fighting game. The reason I compared it to light-gun games is that it uses the exact same mechanic; pointing and 'clicking' at the baddies to whack them with your katana. So if you were hoping for a truly motion-sensitive game involving swinging your sword, you will be a bit disappointed. Waving the wiimote in certain directions allows you to perform certain attacks but it is certainly not a direct translation of your movements to the screen.
