Holy freaking cow! The first time I played through the game, I was on composite, and while it was a great game, the colors seemed really washed out.

I got component cables not too long ago, and put Okami in tonight, just to see how it looked. It is awesome! The colors are so much more vibrant. The way the game is rendered places a much higher stress on color than most games, so having the extra colors in there is really nice!

I would seriously suggest you get them if you can use them. I got mine for $10 shipped.
