Hi. I am a little late to this thread. If you are looking for a Zelda-like RPG, Okami and Darksiders are both great choices. Both are some of my favorite games. I've played both and really enjoyed them. But if you are including GameCube games on this list, I see on obvious oversight.

The Sands of Time trilogy of Prince of Persia...Sands of Time, Warrior Within, and The Two Thrones should definitely be added to the list. Zelda is my favorite game and Prince of Persia is a definite Zelda-like RPG. It has dungeons and puzzles that are very reminiscent of Zelda. The Prince of Persia: The Forgotten Sands was also released to the Wii. All excellent games, like Zelda.

Because of Operation Rainfall, we are also left with a gem on the Wii. Pandora's Tower was a lot of fun. It was basically the Wii's swan song. It was GREAT.

Also, if I'm not mistaken, Beyond Good and Evil was also released to the GameCube. It is ALOT like Zelda. Zelda is my favorite series of games, so I am always on the lookout for great games like Zelda. These are a few of my choices. These games should keep you busy for a while.;)

I hope that this helps. :)
