On the second-tier front, I'd like to nominate the Hobbit. It's a decentish Gamecube platformer (of the Zelda-clone persuasion) that has good music, and it still can be obtained fairly cheaply. Also, Viewtiful Joe...
Two more recent Wii third-party games I'd be interested in nominating: A Boy and His Blob, and Little King's Story. I didn't complete the former and haven't played the latter.
Also, I'd still like to nominate Majora's Mask for some point in the future, but I could understand that there will probably be a good deal of Zelda fatigue at this point, anyway...or at least by the time everyone has played through Skyward Sword.
