I love all things Apple, so I was like a kid in a candy shop when I found this website to download mac games.  Best of all, they are almost all $20 or less!  I downloaded Devastro and Virtual Villagers, which is like the Sims on an island.  I take my MacBook with me everywhere so I need games to keep me occupied when nothing else is going on. 

The games are a small download so you can even download them over Wi-Fi if you're at a coffee shop.  True nerd bliss.
