Mac Games Sites
Here are some links to the places I've been getting my games for Mac.
Azada is fun coz it has different kinds of puzzle games to solve which collectively "beat" the game. It's free to try but 20 bucks for the full version. I don't remember where I got it but it comes from Big Fish.

This site has freeware. I've played Frozen Bubble. Typical aim & shoot kinda thing.
