Four years ago, Blizzard Entertainment released World of Warcraft, one of the most absorbing, in-depth massively multiplayer online role-playing games (MMORPG) to ever hit the market—it currently boasts a subscriber base of more than 9 million players. Now the company is casting more magic with Wrath of the Lich King, the second expansion pack for the ever-growing fantasy universe.

Few games are updated eight years after their release, but few games are as timeless as Blizzard’s classics. StarCraft, Diablo II, and WarCraft III all run on current Macs, even though all but WarCraft III launched before Mac OS X. You don’t even need to keep a pesky CD in the drive to play, making these low-system-requirement titles great for the drive-free MacBook Air. Follow our easy steps to get your original game discs running on a current system--even when you don’t have the discs around.
