An update...
Very nice game...fully recommended.
Don't expect a regular RPG though. It's fairly linear and it's pretty much like playing one of those 'gun games' at the arcade. Every stage you move forward and have waves of monsters you have to deal with. Certain conditions affect your rating at the end of each stage ie. your completion speed, the damage you take, if you allowed any monsters to escape etc.
The rating affects your bonus at the end which is usually raw materials, allowing you to forge your sword into a new one.
Of course you gain XP, have a companion who helps you out and also gains levels, and you gain some new sword techniques which all involve a pre-ordained movement with your Wiimote. I find it hard slashing diagonally though...
I spent a day suffering from muscle pain in my arm today.....you really do need a break after a few hours when playing this game.
Kyu
P.S. You have a shield to block with, which starts to break when it takes too many hits...between blocking, slashing and targeting monsters, it's a very active game!
