It's been a LONG 10 years since I played the alpha of Half Life for Mac. Let's hope this is a new beginning for Mac Gaming. If they have figured out all the tricks they need to pull off the same kind of graphic quality with OpenGL that they have with DirectX maybe we can look forward to Bungie bringing the Halo series out for the Mac as well.
Hey... stop laughing! 5 seconds ago you would have said the same thing about Steam coming to the Mac.
