A warm welcome to the Adventure Genre
Take Zelda and turn Link into a wolf and have him restore light and destroy darkness...wait that already happen...oh well. It is said the director of Okami is a big fan of the Zelda series so you will see subtle similarities Between the two games. But Okami offers an unique experience that any fan of Adventure genre should check out.
What makes the game different from Zelda is the Celestial Brush. It allows you to bring up a brush and manipulate the world around you. If its night, you can draw a circle in the sky to make a sun, to make it morning. Theres a broken bridge, just skribble in the blank to make it whole again. It really comes into play for solving puzzles but it does play a part in combat. Just a stright slash across the enemy for big damage.
You use the Brush by holding down the B button and then drawing it with the Wiimote. The whole thing isn't perfect. At times, you may be doing draws over again because the game doesnt reconize your doodle making it diffcult especially in combat. Combat is also done with various weapons. You attack by wiggling the Wiimote. But what prevents you from waggling the mote like a mad man is the game combo system requires you to rythmicly move the mote to chain attacks. This combat more engaging than just a waggle fest.
I can't recommend this to everyone. If your not a fan of adventure games like Zelda, theres nothing much different here for you to get into. But If you like Zelda, I couldn't recommend a better title.
