How many games are there for the wii?

A lot. And still coming out. If its so important, you can count them, but I doubt you'll make it in the near future, and I doubt that youll be able to get the names of ALL Wii games...

I found a list of all current wii games( 31-12- 2009)

i counted to about 900 games, many of them being remakes of others succh as crash of the titans, Call of Duty, Bionicle heroes but approximently 900 different games
