The story is compelling enough to make playing through all three worthwhile, and the campaign difficulty is tiered so that each is more challenging than the last.
Starcraft offers a lengthy single-player campaign featuring ten missions for its three diverse races, totaling 30 single-player missions in all (there's also an unsupported veteran campaign included as part of the campaign editor). It doesn't stray far from the blueprint created by its predecessors (namely the Warcrafts and Command & Conquers), but it is, without a doubt, the best game to ever adhere to that formula.
Weighed on its own merits, Starcraft is an extremely well-crafted game, albeit one with a few notable problems. Let's face it: Starcraft comes with a great deal of anticipatory baggage, and it would be easy to say that it's either a huge disappointment or the greatest thing since real-time strategy became a household phrase. Passing judgment on the most eagerly anticipated game of the last few years is no easy task it's difficult to set aside prejudices that would sway one's opinion either way.
