Haven't seen it mentioned yet, so I'll throw in Ghost Squad. Probably the best lightgun game on Wii, short but sweet. And cheap ($29 at launch, you can probably find it under $20 now).
Metal Slug Anthology's a great value (as are all the SNK collections) but be warned that (a) it doesn't have Classic Controller support and (B) image quality isn't as nice as D4's Virtual Console releases (which output in true low res).
Also, Kororinpa is pretty expensive these days, so if you want a tilt puzzler you may just want to go for the superior sequel (Marble Saga).
