Taking place four years after the events of StarCraft: Brood War, StarCraft II pits Jim Raynor against the Terran Dominion and its Emperor, Arcturus Mengsk. However, a terrible foe has re-emerged after four years of silence, bringing with it a shadow of a greater evil to come.
SpecsUpdate
Pros
Pro Well balanced, asymmetrical gameplay
Opposing teams will have completely different skillsets allowing players to take wholly different approaches toward completing the same goal. This makes for asymmetrical gameplay that has been painstakingly balanced.
Pro Campaign features an engaging story and acts as a tutorial
StarCraft II tells a very concise and cohesive story, exclusively featuring the Terran, with some exceptions during optional missions. During the campaign, the player is asked to make several choices which partially alter the storyline, as well as give access to some units, while making other completely unavailable. With a new unit unlocked nearly every mission, these levels utilize unique gameplay mechanics that highlight the specific uses of each new unit that is unlocked, thus allowing players to familiar with them. For example, one mission highlights the maneuverability of the Viking, an aircraft that can quickly fly across the map, killing other aerial units, and transforming to become a walking vehicle that can annihilate ground-based enemies.
Cons
Con Starcraft I units are unavailable
They removed/replaced some of the units with new units. As of 2021 several mods of SC2 engine feat SC1 units are freely available
