I got Okami (wii) on release date in the UK after hearing all the great reviews of Okami for PS2. While I thought the game was great (design/music/story etc) I didn't feel it lived up to the "good as/better than Zelda" hype. In my view it didn't come close to Zelda... in fact it didn't really remind of a Zelda title.
That's not to say I didn't enjoy the game, I'll be buying Okaminden on its release outside of Japan - assuming it has one.
