Tuesday Has No Phones

My boss got his kids a Wii for Christmas (or at least that's the official story. How much the kids have actually gotten to play with it is another matter... ;) ) Anyway, he's not much of a tech geek so he doesn't know what all is out there. He and his wife liked bowling and tennis, and his oldest son (who is 7) absolutely loved Lego Star Wars. Actually his oldest son loves Lego anything.

I do not own a Wii myself, but I know many of you do. So - got any recs for games? For him or his kids.

Thank you!
