i borrowed my friend's wow cd and installed both original and the expansion into my pc. when i sign up an account, i need a retail box authentication key. so i plan to buy it. since i have both original and the expansion, do i need to the expansion game too? or i only need to buy the original Wow game?
by the way, can i just simply go buy the 60 days game card? or do i have to buy the whole game?
