Metacritic has put together a list of the top 5 Wii games of the year: http://www.metacritic.com/games/bests/2008.shtml
1 - Super Smash Bros. Brawl
2 - World of Goo
3 - MaBoShi: The Three Shape Arcade
4 - Okami
5 - Tetris Party
#3 hasn't been released in the states yet, but looks really interesting...and is likely to show up on Monday, just making the end of the year. Interestingly, after all the maligning of WiiWare, 3 of the top 5 rated games per Metacrtic are WiiWare games. I'm not surprised personally, WiiWare is horribly under-appreciated.
I grabbed the next 5 (well 6) from Metacrtic for the year as well:
6 - Guitar Hero World Tour
7 - Bomberman Blast
8 - Art Style: ORBIENT
9 - Boom Blox
10 - Mega Man 9
11 - No More Heroes
3 of the next 5 are WiiWare titles as well, bringing the total to 6 of the top 10...and Strong Bad, Lost Winds, Dr. Mario and Final Fantasy aren't even on the list.
So point one - WiiWare is under appreciated.
Point two - Innovation on the Wii is under appreciated. From that list of 10 I'd say at least 4 of them are innovative and different than what we are seeing on other platforms (World of Goo, MaBoShi, Art Style: Orbient, Boom Blox).
I've heard complaints that the Wii was supposed to change gaming, but it is failing horribly. I disagree with those sentiments of course, and I think the variety found in the Top rated Wii games is proof of it. (also interesting is the DS list - World Ends with You, Professor Layton & the PSP list Patapon, Space Invaders Extreme).
...but I'm really not missing them.
I enjoy the occasional shooter, but I have to say, the Wii Top 5 list is far more diverse and interesting to me than the Top 5 list on either of the 2 shooter consoles.
