What if Classic versions of expansions had been around since the launch of WoW?
The Burning Crusade Classic is launching, but WoW Classics version of original World of Warcraft is still available. Its a new kind of expansion release for Warcraft. In the past, when a new WoW expansion has come out, there have always been players who dont buy it right away, often because of the price barrier. But even if players dont own the expansion, they havent playing the previous expansion  theyre pushed into the changes of the new expansion. Most notably, the changes of the world with Cataclysm. But BCC is different. Players can play BCC or stick to Classic or both.
