If you keep up with Kaalus's blog, you may have read that SC will soon be playable on your PC!!
Kaalus says: "With the new engine, there is support for new platforms! Namely Windows
Phone 8.1 and Windows Store. I will be submitting 1.27 there soon."
Now, in order to play SC with your keyboard and mouse, you have to have Windows 8.1. This is a big step for SC! If any of you have Windows 8.1, tell me what you think about playing with keyboard and mouse ;)
