Wanna play the best RTS of the 21st century? if so you should buy this right now
it is the single most impressive RTS campaign i've ever seen, if you remember warcraft 3 it was pretty amazing back then right?
well, this is even better.. esp the terran campaign
you'll enjoy every moment of it
as for the zerg campaign, it's pretty good too, although not as good as wings of liberty, each has it's own charms
