Where do you get Mac games? THE INTERNET. It's called MacGameFiles.com. Go to any decent self-respecting computer store and there'll be whole isles of Mac games. (Notice I say "decent" and "self-respecting." This does *not* include Best Buy/CompUSA.)
If you are talking about an apple store, the closest one I have to me is 3-4 hours away. I used to do that for the amiga, but I ain't doin it any more.
