I didn't really care when I saw that Valve would be bringing Steam to the Mac, but then I realized, they have quite the selection of games. I'm actually quite excited about it. Great games like Bioshock 2, Mass Effect 2 and Modern Warfare 2 are on there, but above all, Unreal Tournament GOTY is there!!! Maybe the tide is changing. Guys, I think Mac is really starting to become a gaming machine.
