Honestly there are a couple of them that I really liked (No More Heroes for example) but so few of them are worth playing.
Anyway I didn't buy a Wii for 3rd party titles and I won't buy a Wii U for 3rd party titles either.
That's why I've never been disappointed by the Wii 3rd party library. Coming from the N64 and then the Gamecube I wasn't expecting things to change and I was right.
