Starcraft 2: Starter Edition
Starcraft 2 is one of the finest games you can get for the Mac. That you can get a full Starcraft 2 game for free is jaw-dropping. This strategy game sees you controlling three different races: Terrans, Zerg and the Protoss. Each race has different weapons, craft and abilities (and each feels magnificently different to play). You wage battles against one or two of the other races. You'd be a fool to pass this one by.
There's a great narrative story, and you can a lot of the missions from the full game in the Starter Edition. Enough for it to warrant being a full game in itself. You can also play other gamers online, and it's a great multiplayer experience.
Team Fortress 2
This is the gold medal award. Team Fortress 2 is an amazing well-balanced online shooter with a wonderful cartoon style. Even though Team Fortress 2 is a multiplayer, it's easy to jump in and start playing on your own. It's ridiculously good fun, with a range of genuinely different character types. You'll soon become utterly addicted to helping your team win each shootout.

This game from iOS makes its way to the Mac in style. Touchgrind is a skateboarding game where you place two fingers on the trackpad to guide the skateboard around. It's a real test of skill, but also an innovate control style that makes a great change from the usual mouse and keyboard routine.
