If you're going into Okami as a fan of Zelda you may be dissapointed. Dungeons are minimal, puzzle solving is minimal (the game will solve them for you by telling you how to do it, without fail, every time), and game play depth is minimal. The best things about Okami are aesthetic and story. I wouldn't go into it at all for game play.
I got it and played for like 30 hours / 1.5 Okamis and then mothballed it. way too much game. hopefully someone fanpatches out the bug one day
The pacing is the worst thing I've seen in a game. It never ends. It is like the anti thesis to the rest of Kamiya's games. Whereas DMC, RE2, Bayou, and VJ are about tight mechanics and short, compressed game clocks Okami is about being a mechanically vapid and as long winded as possible. The bug really does ruin it.
