The tilesets are pretty sweet. But I got used to it quickly. My favorite tileset would have to be the Shakuras Homeworld set. You can see units distinctly, and the doodads and ramps also look pretty wild. In the first episode, you command the Protoss exodus from their homeworld of Aiur to the Dark Templar world of Shakuras.
Old heros become new foes as the plot takes shape.
As with the original game, the story behind Brood War is a good one. I never felt my missions were pointless conquests. The Terran stance is no longer one of defense and survival. The next episode takes you on the crusade of United Earth Directorate Admiral Gerard DuGalle. You face off against both the Zerg and the Protoss with your newly equipped Goliaths, Medics, and Valkyrie Frigates.
