xxxJonBoyxxx is describing the multiplayer aspect of SC1. You are describing the single player campaign. In the multiplayer aspect of SC1 there was the option to have a strategic element where you had star systems tied by star lanes. You secured star systems as choke points and for resources and when enemy fleets moved in there was combat which was like a single ship Super Melee mini-game between the two players. Something akin to Archon. There is nothing like that additional strategic layer in the SC2 multiplayer mode, though since we do have UQM I would love-love-love to see it added.
