I don't see why you would want to, but yeah I suppose you can. Just go to battlenet.com and download the game client for your account again.
starcraft 2 Wings Of Liberty has already come out, but the other expansions haven't come out, unfortunately...
2 reasons. 1 you didnt install it or 2 you dont have a battlenet account
12 to install and at least 2 for save data
starcraft 2 map creator, it should comw with starcraft 2
My oppinion: Starcraft 2
You probably know the answer yourself now but, no, they haven't cancelled it. It, infact, has already been released.
StarCraft 2 is coming out on July 27, 2010,
Although I haven't played Starcraft 2 before, I'm assuming it will be nice, considering Starcraft 1.
yes you can. But you can only access your account from only one computer.
Assuming you are talking about Starcraft 2, the answer is: absolutely. The game has already been released and can be purchased via Blizzard directly or through third parties such as Amazon or GameStop
No they are not.
starcraft is a prequel to starcraft 2
