When you buy the world of Warcraft CD is the rest of the game free
There is no rest of the game. You buy the game, you register, you pay a $16 a month subscription fee (included updates, support and loads of content.) If you can't afford the subscription, Warcraft III The Frozen Throne is available and it's a one time licensing cost. You just play it by yourself.
