Once again we are delving into taste, I personally think it is ludicrous you suggest that you can't find that many Wii games to own even WITH Virtual Console. There are some true classics on Virtual Console and they aren't worth owning by people?
I can't give Nintendo any credit for Virtual Console outside of Sin & Punishment, since that's the only VC game that required any notable new effort to get over here that I actually care about. But since you're looking for a number, here are the games that I think are "purchasable" (i.e. not a total waste of cash):

So there you go GP, I think that there are 147 individual games worth playing on the Wii. But if you're giving Nintendo a pat on the back for making you pay five bucks for a game they released 23 years ago, I suggest you rethink that position.
