What system should I buy Okami for?

[CRTGAMER]

PS2 version. For the controls and convenience of a hard drive install.

Go with the Wii version, it adds to the experience IMO, and it is superior to the ps2 version.

You can load games off of a hard drive on the Wii too.

I believe the Wii version does not show the full ending of the game. Having not played the Wii version, I can't verify that. However, if it's true that should pretty much end the thread IMO. I know I certainly wouldn't want to play an incomplete version of the game. Always go with the originals I say, with some exceptions(I think the Dracula X Chronicles version of Symphony of the Night is the best)

As a recent Wii owner, I can say that motion controls are a bit overrated. Yes, they work great in some games, but Okami, Resident Evil 4 and Twilight Princess play just perfectly without them and they should, as they weren't designed with them in mind. I am more interested in seeing Wii games built from the ground up with motion controls in mind

Does the Wii still require the game disc inserted after it is installed?

From wikipedia:

The final credits movie that was in the PlayStation 2 version of the game was removed from the Wii version, much to Kamiya's regret as it removed the omoi—"a combination of thoughts, emotions, and messages" — from the game: "[The staff roll was] the omoi of everyone who worked on the project, put together in a moment of bliss held out just for those who completed the journey. It was a special staff roll for a special moment. And now it is gone. All of it. ...It's incredibly disappointing and sad."[68] A Capcom representative noted that the credits, a pre-rendered movie, had the Clover Studio logo within it, and they had "no legal right to use the Clover logo in a game they were not involved with directly". Since they also lacked the source to the credits, they opted to remove them entirely from the game.[68] Ready at Dawn's co-founder Didier Malenfant stated that the Wii version of Ōkami took up much more space on the game media than the PlayStation 2 version, and that the movie was cut in order to fit everything on a single game disk.[69] The credit sequence was restored in the Japanese release of the Wii version[70] and revealed that the port was co-developed by Tose, having provided additional planners, designers, programmers and test players.[1] The images from the credits, although not the credits themselves, are still available as unlockable art.
Players have discovered that the cover of the North American Wii version of Ōkami includes a watermark from IGN, and traced the source to an image taken from IGN's site.[51] To make up for the error, Capcom offered for a limited time to replace the cover with one of three high-resolution covers free of charge to users in North America.[71][72] Due to delays in fulfilling the offer, Capcom shipped copies of all three covers to those that registered.[73] They have since discontinued the offer, but have made the cover images available worldwide in high-quality PDF files for users to download and print themselves.[74] The European PAL version of the cover has no such error.

I'd say one big factor should be whether you want widescreen. Drawing lines in the Wii version is easy if you use Z instead of A. I think the filter can be gotten back if you turn off the LCD mode. Not sure though. The colors are MUCH more vibrant vibrant in the Wii version. I think I remember an interview where Capcom said that the PS2 simply wasn't capable of putting out the true colors of the game. The ending credits can be watched on youtube.

Drawing with the brush in the Wii version is MUCH faster. You may never mess up on the PS2 version, but that's because it moves so slow that you'd simply have to suck to do it. You get good at the Wii brush strokes eventually and it makes pulling them off much more intense and rewarding. The battle controls take a bit of getting used to, though. Like some other people said, the dodge simply doesn't work. I didn't care though. It's not a difficult game. You're never really needed it in the first place and you won't feel like you got some inferior version of the game because of it. My friend Lucas who played the PS2 version all the way through felt upset when he saw how much more vibrant the Wii version's colors were. He thought his was the inferior version. Just remember, use Z for straight lines. They tell you in the manual, but not the game.

I believe the PS2 version was more colorful and vibrant too.

Nope .

I'm not sure. I think not though. My friend modded his wii and usually doesn't have a disk in it when we play brawl.

No.

Edit: Assuming you know that your Wii must be softmodded (very easy) to do this. You can't just plug an external drive to your Wii and start ripping.
