I really enjoyed those from your list:
Disney Epic Mickey
The Last Story
Little King's Story
Muramasa: The Demon Blade
Ōkami
Zack & Wiki: Quest for Barbaros' Treasure
plus (not on your list):
Sakura Wars: So Long, My Love
The Sky Crawlers: Innocent Aces
World of Goo
but the Wii was first and foremost an excellent 1st party console, so I don't think we need to discuss the quality of its 3rd party support anymore.
In case the situation changes with Wii U - i.e. it will get very good 3rd party support in addition to the excellent 1st party support - it will be my only console next gen.
