Okami... What's the best way to explain this game? You're the sun goddess reborn, as a wolf, to rid the world of Orochi and evil. Sound familar? Well, it shouldn't, unless you're seriously into Japanese mythology. This game is saturated in it, and I, personally, couldn't see this game any other way.
Let's begin with the game's unique system. On top of the normal mechanics of the game, which can only be properly compared to the Zelda series, there's also the unique brush techinque system. Pressing the L1 button (I believe it is) turns the current veiwpoint into a canvas, and you are free to draw as you will. For example, you draw a circle in thesky for a sun to appear, or a big bold slash across the screen to destroy rocks or decimate teh enemy. While the brush aspect is very fun and useful, unfortunately the controls can be very finicky, and can sometimes not pick up what you're trying to do, leading to frustration during battles or when you have to conserve your ink bottles (what you need to use brush techniques).
Now, you can't talk about Okami without talking about the graphics. While graphics usually don't matter that much to me, I have to say the graphics in this game are breathtaking. The beautiful ink drawing-esque style of this game is amazing, and it fits the game's subject matter perfectly. The best part? It's like this the whole way through. It's not like many games, where it saves its best for only certain parts, while the rest of the game looks medicore. Soemtimes, although rarely, the game can show some lag, although it's never during the important parts, usually while running through the towns, so it's forgivable.
To close, Okami, to put it bluntly, is one of the best games to come out for the PS2 this year. The game is almost perfect in everyway, and there could be no better way for this to be Clover Studio's swan song.
