are there enough wii titles available now to make wii a worthy purchase?

Depends what your friend wants. Each system this gen is worth a purchase, but it depends on your tastes and what sort of gaming you prefer.

What I would do is have your friend compile a list of Wii games he's interested in that are out now. Once he has that list, he can decide if he wants to pay $200 play those games. That's really all there is to it.
