A fantastic port of a well beloved game. Okami is a game based losely around the Japanese mythology, done in the style of artistic brushwork. Definitely worth the time and effort.
Graphics - where do I begin. I really loved the style of the visualisations of Okami. With a clever use of cell shading, this whole game turned into a classic style of Japanese art, which really suited its purpose. Low resolution wasn't so much of a problem in this case. The graphics were well suited for each environment - you could really feel the nature just leap out at you, and also feel the temperature changing from each different environment. Certainly the transition from PS2 to Wii was a smooth one.
Gameplay - what I really loved about the gameplay was its simplicity. It was easy to maneuver, and easy to attack. Everything was quite fast paced and it all fit together beautifully. What really amazed me was the added functionality of drawing the symbols rather than just using a control stick like on the PS2. And for those wondering about drawing straight lines - never fear, they've done something about that (so everyone can draw a straight line!) One of the main perks about this game is its length. Though for some people, they may eventually get bored whilst halfway around the game, but as most Wii owners know, a long Wii game is a rarity.
Music - Perhaps my judgment may be a bit biased, but I definitely loved this game's soundtrack. Its style was written around a traditional Japanese style (with orchestral influences) to make something truly original and well suited for the game. Each battle was tense and epic, and the open fields relaxing yet grand. Definitely one of the more memorable soundtracks.
Overall, a great port to the Wii. For anyone a fan of Japanese themed/styled games, Okami is definitely a must have. However, there is now a port on the PS3 with a much higher resolution if you think that graphics may perturb your experience (though I trust it wouldn't do so much).
