Re: Free World of Warcraft
Why are Diablo, SC and warcraft 3 free to play online? Because all youre doing is useing the battlenet hub to connect to the other players. All the cpu useage, bandwidth, etc is comeing from the Host (You, if you started the game), with the exception of D2's realm characters, in which they simply store your character file so you cant hack it. The costs and data storage there is minimal, instead of the countless terrabytes flowing off a WoW server on a daily basis, not to mention the actual hardware being taxed by so many players.
For a better anology, its like calling someone. The switchboard takes you call, connects you, then goes to the next call, leaving party a and b to talk to each other without any more assistance from the switchboard. In most MMO's you would be required to be connected to the switchboard at all times, along with everyone else playing the server.
