Wii Warm Up: The second tier

Let's put aside the big three for a bit. We all know everyone wants Metroid, Smash Bros. and Super Mario Galaxy. Oh, and Wii Fit. There are a lot of lower-profile games coming out this year that are every bit as compelling. We're thinking about stuff like NiGHTS, the Nintendo-published Endless Ocean, and-- why not?-- even Namco Museum Remix. Someone out there must be more interested in Dewy's Adventure, for example, than Metroid Prime 3.

What about you? Which one of the "smaller" upcoming games has done the best job of capturing your attention?
