Wikipedia says SC sold over 9.5 million. So it could be over 10 million. The citation at Wikipedia for that figure, links to an IGN article, which only mentions sales through 1998. Likewise vgcharts does not have SC data to my knowledge. It would be helpful if we knew just how many copies SC 1 sold. I heard a lot of people have bought SC since the announcement of SC2 & due to it being on sale recently.
