Wow! Okami is completely different from other games!
Third the game play is totally different from the others. As you know that it is the creators of Viewtiful Joe so that means the game it going to be different from the others. Not just being a holy dog, you can control the world with your magical brush. Hold the R1 button change the game play in to a painting. With your brush you can do anything you want to like you can make a big scratch on the enemy and kill them with one hit or simply press the square button to hit your enemies with the giant sun charm on your back. If you see a dead tree, just make a circle around it and the tree will bloom are make a line on the ground to make flowers. If you see a broken bridge make simple lines and you have a complete bridge. If it is night and you want morning make a circle in the sky and you will have the sun and the morning starts. So it like games on DS where you can control everything.
You can also help the environment by feeding animals according to their food like for sparrow you give seeds and they will like it and become friends with you. Or help the people in the village and their trust will increase in you which make you to get stronger.
The only thing that I didn't like is the conversations. There is no human sound or any animal sound so you have to read it all the time and they are very long. This could have been improved.
I don't have anything else to say more because I have just played about 2 hours. In conclusion I say it is a very fantastic game. I advice the people to buy this game.
