I'm no fan of Macs or Apple, but this could be a huge boon for the PC gaming industry. With Valve and Steam paving the way for cross-platform titles, perhaps the entire industry could boost sales and find new sources of revenue by attracting the Mac audience.
Props, Valve.
Awesome, another way to indulge the WoW addiction. Perfect.
I'm way more excited about playing L4D2 now. The melee stuff sounds awesome.
Wups, double posted.
