At least in the versions I've played, this game was always a little bit buggy. And it's undeniable that SC2 was one of the greatest games ever created (possibly only the Civ series has taken up more of my life than SC2, and that's up to 7 games so far, counting Call to Power and Alpha Centauri). That said, this is a fantastic game, with a good plot, neat ships, and some fantastic tweaks to the original system. Well worth the time!
