I used to have it but I gave it away to someone because I got sick of it (well the multiplayer at least).
Battle.net is composed almost totally of noobs who want to play these stupid maps where you have a spawnfest of units coming out of a bunker and you're supposed to 'win'. Basically a rush fest, you don't even get to enjoy the game.
Or the maps where you aren't actually limited by ore, because there are hundreds of Minerals on top of each other. Then it gets boring.
The single player isn't too bad however. If I were to play it again I'd probably only play it for the singleplayer. (Or multiplayer with people who actually wanted to make the game fun). And only certain missions at that. A lot of the missions are quite generic (escort <VIP> to a base and take over the base and then kill the AI with that base).
However, to me multiplayer is the most important aspect of a game, so I rate starcraft 0 out of 5 stars. It's a generic RTS that can get really boring after a while.
