Silent Hill:SM definitely should be on that list.
All of those mentioned are good. The CoD's are always overlooked but still some of the best on Wii.
Prince of Persia: Forgotten Sands is excellent and probably the most criminally overlooked, specifically made for the Wii game ever. Although I haven't played it, the scant reviews for Driver: San Fransico also looked great, it was a completely original game for Wii (usually a bad thing) but was fully fleshed out and even supported DS hook-up.
My favorites are:
Dewy's Adventure
Prince of Persia: Forgotten Sands
Zack & Wiki
Tatsunoko Vs Capcom
Goldeneye
Boom Blox Bash Party
Red Steel - Far from perfect but I loved what it aspired to do.
Just Dance (series)
Guitar Hero (series)
EA Sport Active - The best exer-gaming that's come out
Tiger Woods - Made great with motion controls
Honourable mentions:
Opoona, Cursed Mountain, Ivy the Kiwi?, Lost in Shadows, Epic Mickey, Mushroom Men, De Blob, Fishing Resort, Innocent Aces (also criminally overlooked)
